I know Traditional Mongolian comes up regularly in i18n contexts, but I've never taken the time to see if it's something an app should support, based on how actively it is used. It seems like it's too minor, mostly due to the fact that nobody could be bothered to support it in electronic formats.

Vertical Japanese is very common in the print magazines I read, and is RTL amongst the rest of the Japanese text which is LTR. I just don't see it much online because of the trouble of setting it.

If I ever have too much spare time I must try to support vertical Mongolian in my app.
