the foreign language speakers here would like to have a word...

Good old codepage to the rescue!

(Yes, I know technically codepage isn't ASCII. I guess you could use box drawing extension to draw foreign language character if you wanted. Or maybe just SVG of the text)

please not codepages. finally being able to write multiple languages in a single document, which is something i need to do frequently, really makes a difference. codepages were a nightmare compared to the simplicity that unicode is in this aspect.

Yes, that's the joke.

They should have thought of that before they put non-ASCII characters in their language.

... but they couldn't...
