WINEDEBUG=font console output

The problem was noticed first in an installer, but it's visible even in
regedit, but there only with menu font.

Currently on 6.0-rc1.

When regedit is run in LANG=ja_JP.utf8 locale (which is not my primary one -
may or may not matter), menubar and menus are full of missing glyph boxes
(except for the bits consisting of latin letters).

The patch that I've sent to the list only consistently worked for 5.21, not
later.
There also may be some randomness involved (maybe due to fontconfig cache), as
in some cases menus did show up correctly in 5.22 with that old patch, but (for
the time being) seems to be consistently broken in 6.0-rc1.
