For a long time I've had my full name as user name on my machine, which meant that my user profile path contains both a space (evil) and a non-ASCII character (even more evil, although it's in Latin 1 at least). A lot of things break on one or both of those things and at times it's a bit annoying to deal with. Some bug reports have also been closed as "Won't fix, just don't do that. Who needs spaces in paths, anyway?". I haven't tried to use non-Latin Unicode in my user name and profile directory, which would break everything that uses the old ANSI APIs on Windows instead of the Unicode ones, and that's probably way too much breakage. But broken nonetheless, and that includes a lot of new, recent, and still-maintained software :-/ In a similar vein, I've also used U+2212 as minus sign in my regional settings. There's a lot of software that refuses to parse numbers it previously happily emitted. I've given up on that too, by now, though. The only thing I still do is using English as UI language (so I don't have to deal with bad translations of software), but German as my regional settings (with ISO 8601 dates). There's a lot of software out there (I think GNU gettext is broken in that way on Windows) that assumes that the way I want my dates and numbers formatted has any bearing on the language I want to see in an application. Many others don't care about the regional settings and use the UI language to also format dates, times, and numbers. That's annoying, but at least nothing breaks, so that's the only deviation from the standard user I still use, to still be able to work.
