And software developers, don't forget to implement the 4 byte characters too please. Utter nightmare dealing with MySQL. I believe 4 byte characters still even break github comments.
MySQL was a Norwegian company at the beginning, but you won't believe. It's one of the worst products when it comes to I18N and especially to Unicode.
They still kind of store unicode text as a chain of encoded utf8 characters, if I'm not wrong. Their stupid command line utility still defaults to LATIN1 for input and output despite my locale clearly saying .UTF-8. People in their IRC channel still refuse to admit anything of this as a problem.
Yeah. We've noticed, to our own amusement, that Jira (we're on an older version) can't handle non-ASCII. Makes entering tickets involving other languages fun.
