Each language prints its text its own way: German opens a quotation low („so“), French sets « guillemets » with a space inside that never breaks, Polish keeps one-letter words such as "w" or "i" off the end of a line. The Proofread tab's Typography card reads the edition's newest manuscript and shows what its language's rules would change: how many paragraphs, the changes by kind, and examples before and after, with each no-break space marked so you can see it. Nothing changes until you apply them.
Applying them keeps the manuscript as a new version, and the one before is kept too: Drafts and revisions (with the Author plan or a Book Pass) shows both, to compare them or bring the earlier one back. While the manuscript editor holds changes you haven't saved as a version, applying waits: save them (or discard them) first, so nothing you wrote is lost. Applying again changes nothing, since text that follows the rules already stays as it is.
What the rules do:
- Quotation marks: straight quotes typed as " become the language's own: “English”, „German“, «Spanish», «Italian», « French », „Polish”, “Portuguese”, «Russian» and «Ukrainian». English single quotes become ‘curly’ too. Elsewhere an apostrophe typed between two letters becomes ’ (l’homme, dell’anno), and other single straight quotes are left as they are, since only you know whether they're quotation marks.
- Ellipses: three dots become one ellipsis (…), or the Japanese ……
- No-break spaces: where the language keeps two things on one line: before a closing dash or an ellipsis, inside French guillemets and before ; : ! ?, between a number and its unit or month, after one-letter Polish words.
- Japanese: a paragraph opening with a bracket is set flush, a title in 『』 isn't set in italics, and a full-width space follows ！ and ？ inside a sentence.
The same rules set every translation the studio makes. They exist for English, German, Spanish, French, Italian, Japanese, Polish, Portuguese (Brazil's), Russian and Ukrainian; other languages are laid out with general rules for now. Numbers are never changed: a decimal point stays as you wrote it.
