This tool applies both: the spacing comes from pangu.js, the library behind the widely used pangu browser extension, and the punctuation rules from the chinese-copywriting-guidelines that many Chinese open-source projects follow. Code spans, fenced code blocks, URLs, e-mail addresses, Markdown link targets and HTML tags are set aside first and put back unchanged, so a README can be run through as a whole.
How it works
- A space is added between Chinese characters and Latin letters or digits on either side, and nowhere else: text that is only English is left as it is.
- After Chinese text, , : ; ! ? become ，：；！？, a full stop becomes 。, ... becomes ……, and parentheses around Chinese become （）; spaces around full-width punctuation are removed.
- Full-width letters and digits such as ＡＢＣ１２３ are turned into ordinary ones.
- Switch punctuation fixing off to add the spaces only.

Common questions
- Why add spaces between Chinese and English at all?
- It is a typographic convention rather than a grammar rule, but a widespread one in technical writing: the gap makes the Latin words stand out and the text easier to scan. It is recommended by the chinese-copywriting-guidelines and by many companies' own Chinese style guides, and it is how most Chinese open-source documentation is written.
- Will it break my code?
- Not code in backticks or fenced blocks — those are protected and returned byte for byte, as are URLs, e-mail addresses and Markdown link targets. Code written as plain text is not recognised: in 调用foo(bar)函数 pangu also spaces the bracket, giving 调用 foo (bar) 函数. Put code in backticks and it is left alone.
- Does it change English punctuation?
- Only when it directly follows Chinese text. Hello, world! stays as it is; 你好,世界! becomes 你好，世界！. A comma between two English words inside a Chinese sentence is left half-width.
The open-source behind it
This tool runs on vinta/pangu.js, released under MIT. If you need the same behaviour inside your own program, that is the library to reach for.
