Punctuation Cheat Sheet

Post from June 3, 2009 (↻ May 31, 2022), filed under Web Development and Art and Design (feed).

This and many other posts are also available as a pretty, well-behaved ebook: On Web Development.

Developing and working with international sites is an interesting challenge, not just because of right-to-left contents. Typographically, there are differences between many locales. To improve punctuation in Google translations I’m using a localization aid that I found so useful to finally share:

Punctuation cheat sheet.

The cheat sheet lists the primary and secondary quotation marks of 51 languages (mostly as per Wikipedia). It also includes information about characters that tend not to be used the right way that often, like dashes and ellipses, as well as notes on the use of decimal points vs. decimal commas.

I’m still working on the document but like it to be of service to more people. Contact me if you like to contribute. A different hosting location and alternative formats are under investigation.

   A minor change:
   Language, ISO, primary, secondary
   English (US), en-us, “”,
   English, en, ‘’, “”

   Instead of tickboxes for decimal separators, you need a numbers page for: decimal points (1?23), separators (1?234?000), negative values (-123 or (123) etc), etc.

   Awesome!

   I’d planned to do the same thing but only in French & English. I hope I’ll can help you 😉.

   Oh, useful thing.

   One more special rule for Russian punctuation: spaces before and after middle dash.

   Blah — blah.

   Thank you! I updated the cheat sheet to reflect some facts I recently learned about (although Swiss decimal separators, for instance, aren’t completely transparent I find), and I also included a few Windows shortcuts.

   Always a fan of cheat sheets.

   Had not thought to check Wikipedia for an article on international punctuation. Heading there next. Thanks!

   How about adding thousands separators to the cheat sheet as well? Wikipedia mentions them on their page about decimal separators too. From their examples of use many of the needed information can be taken.

   The most notable country here would in fact be Switserland, where an apostrophe is used. Something which certain other countries—I’ve seen German friends use it—only do in handwriting.
