I agree that marlett.ttf should be fixed, but I think the patch is
correct, because ...
1. AFAICS bug#3284 is caused by a bug in fontforge that was fixed before
20050502, rather than an error in marlett.sfd. The patch works around
the broken fontforge.
2. Marlett is not FIXED_PITCH.
3. MSDN says in CreateFont:

The Wine font mapper seems to copy the Win98 behaviour; specifying
SYMBOL_CHARSET sort of implies that the font mapper can fall back to any
font with SYMBOL_CHARSET if it can't find Marlett, which really isn't
4. (Appeal to authority!) Despite the warnings against using
DEFAULT_CHARSET, a googlefight gives
about 53 for Marlett SYMBOL_CHARSET
about 122 for Marlett DEFAULT_CHARSET (apparently including MFC --
