Metaflac UTF-8 fixes (Windows)

Metaflac can now print all console supported characters from tags on the
screen. It also fixes metaflac to be able to import its own exports back
without non-ascii characters getting mutilated. And --no-utf8-convert
now works properly with import and export commands.
