The FixedSys font is not a Unicode font, so what happens is that the
console display switches into codepage mode and automatically maps all
Unicode characters not in the font's codepage to some approximation of
them, where possible. For hyphen and minus that works well, but for
most characters it doesn't. You'll just get question marks instead.

It is supported just fine. Mintty does have a special hack to map
U+2010 to plain '-', because most fixed-width Windows seem to be
missing that for some reason, but U+2212 is present in all the fonts
I've tried, except of course in non-Unicode fonts. For example,
Consolas, Courier New, and DejaVu Sans Mono all have it.

Bottom line: use a Unicode font for UTF-8.
