Guidance for Chinese Traditional

Guidance for Chinese Traditional

1. Capitalization

  • In case of capitalized letter for a name, a person, a product, a place, or any similar scenario, do not translate it but leave it as it is.
  • Check the context and understand what matters the most in the sentence. Capitalizing is impossible for Chinese characters, yet no wrong with emphasizing the term.

Capitalize proper names
:point_right: Proton Mail
:point_right: Proton VPN
:point_right: NetShield

Do not capitalize

  • Internet addresses (domain names)
  • e-mail address

2. Gender

  • In Mandarin Chinese, there is no distinction made between the words sex and gender. Terms like “gender registration” or "legal gender” are referring to biological sex. :point_right: 生理性別 : 認同性別 = Sex : Gender
  • The wording and tone of the translation must avoid discrimination against gender.

  • You can use passive language to avoid gender-specific verbs, but only if it doesn’t hurt readability and/or make the sentence sound unnatural.
  • Apply the masculine form when an adjective, verb, or another part of speech refers to multiple nouns with different genders.
  • Rephrase when you are unable to find a gender-neutral way.
  • The gender and number of an acronym are determined by the gender and number of the translation for the governing noun of the extended form.
    :point_right: “parent folder” is masculine because the translation is “父”系資料夾
    :point_right: CD-ROM Mastering is feminine because the translation is “光碟“母“片”

3. Abbreviations

Whenever possible, avoid using abbreviations.
Abbreviate the text only when you lack space (mainly buttons, option names or strings with specific character limitations) or when you need to ease the text readability. Instead of abbreviating (e.g., 4 or 5 consecutive words), summarize a term or a phrase in 2 or 3 words that can be written in full.

General criteria for shortening words:

  • Omit at least two letters
  • Truncate a word so that it ends with a consonant and place a period after it
  • When a word contains a double consonant, truncate it at the second one and place a period after it
    :point_right: 電子郵件 => 電郵
    :point_right: IP 位址 => IP

Days abbreviations (in calendars, agendas, timetables… the names of days are written without a period for visual purposes):

English Translation Abbreviation option 1 Abbreviation option 2
Monday 星期一 週一 一
Tuesday 星期二 週二 二
Wednesday 星期三 週三 三
Thursday 星期四 週四 四
Friday 星期五 週五 五
Saturday 星期六 週六 六
Sunday 星期日 週日 日

4. Acronyms

  • Common examples are VPN (Virtual Personal Network), DNS (Domain Name Server), HTML (Hypertext Markup Language), etc.
  • The most common acronyms and their translations are included in the glossary. Always refer to the glossary when localizing acronyms.
  • Commonly used acronyms do not need explanations (DVD, LED, TV, etc.).
  • When an acronym is repeated several times in the same section, include its extended form in parentheses only for its first occurrence.

5. Pronouns

Mandarin Chinese has many words with the same pronunciation and different meanings, and even different pronunciations of the same word represent different meanings. When translating, try to avoid repetition of a single word in the same sentence, especially the use of “you (您)“, and the basic politeness will not be discarded because of informal translation.

6. Gerunds (“ing” ending)

  • Gerunds are used in English, such as in “Creating a report”.
  • When paragraph and chapter heads begin in English with a gerund, as a general rule please use an infinitive, translating it as the equivalent of “Create a report”.
  • But depending on the context, this may also mean “in the process of”.

7. Punctuation

  • The first half of a pair of punctuation marks (such as (, ", <, [, {, ", ', etc.} must not appear at the end of the line; nor should the second half appear at the beginning of the line.
  • There should be no punctuation at the beginning of any line or on a line by themselves.
  • In the event of untranslated passages, please retain all text and punctuation formatting in the original text.
  • Headings do not take punctuation (such as quotation marks or a period), except that a comma or enumeration comma (、) may be added to an overly long heading.
  • Manual and chapter titles use corner quotation marks 「」.

7.1 Period

For the period at the end of a sentence, adapt the source to your language usage.

7.2 Exclamation mark

  • Exclamation marks are used to give emphasis.
  • As their use is less common than in English, you should use them sparingly: feel free to change an exclamation mark into a period if it is more natural, but please don’t change a period into an exclamation mark.

7.5 Colon and semicolon

  • Colons and semicolons are all preceded by a non-breaking space.
  • No need to add the extra period “。” at the end
    Date: Old to new :point_right: 日期:以舊至新排序

7.6 Em dash (—), en dash (–), hyphen (-)

  • In English, an Em or En dash is used to demarcate an isolated element, to introduce an item that is not essential to the sentence’s meaning, to emphasize a sudden change in thought or to bring focus to a list.
  • It is often more appropriate to use a comma, a full stop or parenthesis instead.
  • Also, the Em dash is not used for date ranges, therefore you should use “至” instead.
    September 10 - 20 :point_right: 9 月 10 - 20 日

7.7 Quotation marks

Always use Chinese corner quotation marks 「 」 (and 『 』 for a quote nested inside another). Do not use full-width or half-width English-style quotation marks ( " " ).
:point_right: 「範例」

7.8 Apostrophes

Use straight apostrophes :point_right: User’s Contacts = 使用者的通訊錄

7.9 Ampersand (&)

Replace “&” with “和”, “與” unless it is part of a company/product name or a registered trademark.

7.10 Half-width & full-width space

  • Use half-width space:

    • Special symbols such as @, #, $, %, &, *, =, ~.
    • Between Chinese characters and English characters
    • When English characters appear in parentheses, but there should be a half-width space between the words before and after the brackets.
  • Use full-width space:

    • When Chinese characters appear in parentheses
    • Within the documents, such as comma (,) or (、), period (。), colon (:), question mark (?), upper and lower quotation marks (「」)…
  • Except for periods (。), commas (,), and the enumeration comma (、), which must be centered full-width, other punctuation marks should be half-width. Chinese abridgment marks (…) shall be replaced by English abridgment marks (…).

8 Spacing and non-breaking spaces

  • Use non-breaking spaces to prevent improper division of elements such as product names, part numbers, numbers, dates, etc.
  • When using currency symbols or units of measurement, include a non-breaking space between number and sign.
  • To insert a non-breaking space using your keyboard:
    • On Windows, hold down the “Alt” key while typing the number “255”.
    • On Apple, Control + Option⌥ + Space bar.

9 Numbers

  • No need to replace the period that stands for the decimal point in American English with a comma in your translations.
    3.75 :point_right: 3.75
  • For numbers smaller than 1, always put a zero before the decimal comma.
    .5 :point_right: 0.5
  • The period in app/software version numbers remains unchanged.

  • Arabic numerals — including decimal points, thousands separators, and mathematical operators — otherwise keep their original English format.
  • Keep special symbols (@, #, $, %, &, *, =, ~) in their half-width (ASCII) form. Preserve any high-ANSI accented characters from the source (e.g. â, ã, ä) as-is; if such a character cannot be displayed, substitute a half-width-parenthesis form instead (e.g. (R), (C), ™).
  • Time and date:
    • Hours and minutes are separated by a colon. Use the 24 hour format to specify A.M. and P.M.
      at 9:25 P.M :point_right: 在 21:25
    • For dates: 01/31/22 (mm/dd/yyyy) :point_right: 2022年01月31日 — order the year, month and day according to Traditional Chinese convention rather than the English source’s order (e.g. rewrite “9/11/01” as “01/9/11” or “2001年8月20日”).
    • When using the Republic of China (Minguo) calendar, use the standard format “民國90年9月11日” (Minguo year, month, day).
    • Time may be kept in the original format (e.g. “8:30 A.M.”) or converted to Chinese format (e.g. “上午8時30分”).

15 Foreign words

  • The decision about the use of foreign words (keeping it in English) rather than an equivalent term in your language is based on how widespread the use of the word is. An English term might be recommended when its use has become very common.
  • To find out how common a word is, you can use internet search engines. Search for the English word and for the corresponding translation in your language on your preferred search engine. The number of occurrences in each case will be an indication of how popular the use of each word is. If in doubt for an important term, ask Proton Localization team to make an SEO (Search Engine Optimization) check.
  • Foreign words might be accompanied by quotation marks or italics when their use is not widely spread. However, English words that are widely accepted for use are kept as they are in the original but do not take the ending “s” in the plural case.
  • When foreign words are common and well understood, they can be left in the source language. Where necessary, add an explanation in the target language.
  • Avoid using too many anglicisms.

16 Localizing person names

  • Localize fictitious person names used for explanatory purposes, choosing a name that is generic but not stereotypical.
    Please enter your display name (e.g. 王大明 :point_right: 大明 (例如: 王大明)
  • Do not localize real persons’ names.

The sections below (18–21) come from a separate, community-contributed Traditional Chinese localization manual and have been merged into this file.

18 Accuracy and consistency

  • Content must be translated accurately, with no mistranslation or omission, and translated content must be reviewed.
  • Pay special attention to specific technical terminology (e.g. “Noise” translates as 雜訊, “Traffic” as 流量).
  • Cross-references within content (page numbers, headings) must be exactly correct.
  • Operational content in manuals (headings, labels, menus, buttons) must match the software’s own UI translation exactly.
  • Avoid typos or mistranslation (e.g. “out of order” means malfunction, not a sequence error).
  • Company and product name translations must be verified as correct.
  • Content may be added or removed at the meaning level (not just wording polish) to faithfully reflect the product/service’s functionality, but only when the English original is unclear.
  • Terminology used across a product and its related accessory software must be completely consistent; refer to the Proton Glossary for terms used in the software, and keep other non-proprietary technical terms/phrases consistent as well.
  • For a term whose meaning is not obvious from a literal translation, an original-language annotation may be added the first time it appears.
  • Some common Proton terms have more than one accepted translation (e.g. “archive” as 封存 or 封存檔); if you cannot decide which fits, ask the Proton Language Lead.

19 Specific word choices

  • Use 其它 (not 其他) when referring to things rather than people.
  • Translate “scan” as 掃描 (not 掃瞄).

20 Terminology and tone

  • Wording and tone must avoid discrimination based on gender, age, race, occupation, religion, political belief, party affiliation, nationality, region, wealth, or disability.
  • Follow Chinese grammar and idiomatic expression; avoid literal translation.
  • Avoid overly long sentences, and avoid difficult or rare characters/words.
  • Write for a general audience, prioritizing approachable, fluent phrasing.
  • For operating instructions, prioritize concise clarity, and avoid inconsistent translations of the same operation, which could mislead users.

21 Style: formatting and untranslatable elements

  • Preserve English italics as italics and bold as bold in translation.
  • A capitalized English term (typically a proper technical term, emphasized content, or a software feature name) should be enclosed in full-width Chinese corner quotation marks 「」 once translated.
  • All English text uses half-width characters; an untranslated English portion keeps its original formatting.
  • Product names, trademarks ™, and OS names stay in the original language, as do command lines and code.
  • English text or an abbreviation inside half-width parentheses in the source is left untranslated, and the half-width parentheses are not converted to full-width, but add one half-width space before and after the parenthesis pair (e.g. 動態隨機存取記憶體 (DRAM)).
  • A fully capitalized English word or acronym is not translated.
  • A word formed by joining two or more English words (e.g. “AutoInstall”) is not translated; ask the Proton Language Lead if unsure.
