In response to this question, Is there any difference between 旅行者 and 旅人?, the answerer used ruby for the two pertinent words. I was delightfully surprised to find it's accomplished with simple, self-explanatory markdown:




Japanese SE ignores attempts to do ruby with HTML:




I can't imagine why I would need ruby on Math SE or other Stack Overflow sites, but it would certainly be nice if I happened to need it and it was available. Or it could even be, for all I know, a standard feature of markdown.

So, what is the availability of markdown ruby outside of Japanese SE?

    As far as I know, Ruby is not available outside of Japanese SE. We're trying to get it over at Chinese SE, and it's apparently over on the Community Management Team's backlog.

  • @droooze I just tried to use it on Math.SE (I discarded once I saw it didn't work), but of course I can't see it being useful there. On Chinese.SE, on the other hand, I can imagine it would be quite useful, e.g.,「旅行者{lǚrén}」... oops, it doesn't actually work for pinyin, though maybe that's only because it's got some kind of check for hiragana...

    That syntax you've used only works for Ruby on one character. You have to use a slightly different one for Ruby across multiple characters:「[旅行者]{lǚxíngzhě}」is achieved by 「[旅行者]\{lǚxíngzhě\}」(character \ escapes; remove them)

  • @droooze Ah, I see: 「[旅行者]{lǚrén}」. Getting a little off-topic, I got that pinyin off Google Translate. Is it correct? Commented Dec 10, 2019 at 16:00

    No, lǚrén is 旅人.

Ruby markdown is an add-on, thus it needs to be manually requested and enabled.

That said, other than this (Japanese.SE) site, Anime.SE also supports ruby.
