Not a Wine bug.

The latin characters in jvgasys.fon actually look like that, with thick
lowercase and thin uppercase letters, with font linking disabled. jvgasys.fon
is used as the System font in ja_JP.utf8 locale, in en_* locale vgasys.fon is
used as the System font.

Wine's built-in System font-linking links System to Tahoma and its fontlinks,
but that doesn't override glyphs that appear in the base font. So if you remove
all the entries in your FontLinks registry key (eg added by attach 20749)
you'll see that the latin characters stay the same, but the Japanese-range
characters are reduced to boxes.

The actual font appearance difference is due to the ppem value used for
jvgasys.fon compared to vgasys.fon. vgasys.fon has a ppem of 16, jvgasys.fon
has a ppem of 18. (I don't know what ppem is, see the source of tools/sfnt2fnt
for details, and tools/Makefile.in is the file that controls the ppem values
used for generating the various .fon files)

The ugliness of the font is stated in comment 9 to not be the issue of this
bug, but rather the choice of font to use the glyphs from. And that's working
correctly.
