Comment 1 for bug 188368

Without a built in Tahoma font Wine will actually use no font at all - that's why steam was generating blank characters until people installed a (copied from Windows) Tahoma by hand. All removing Tahoma would do is break things for people who use Fonts that the built-in Tahoma has glyphs for.

On that note, Wine's Tahoma now has cyrillic glyphs, but it still needs Lithuanian, Greek, and probably a few others. See the upstream bug.

I'll probably post an email to ubuntu-devel-discuss asking for help with this.
