When ruby is enabled, we can put hiragana above Kanji characters to show how to read the Kanji characters.
The text editor of user profile lets us preview the ruby as shown in the following screenshot.
However, when I save my edit, the ruby is no longer properly rendered. I think that ruby has not been enabled on the japanese.stackexchange.com's user profile.
Should we enable ruby on user profile page as well? If yes, should ruby be also enabled on all stackexchange.com subdomains?
Note: This feature request might have no significant benefit for us. But I love every single thing is precisely defined. (wink)
