Hello,

I suggest that the registry patch generated dynamically by Wine should not be
saved in the registry files on disk.

That way users can patch their registry and have their patches in effect but
wine would automatically generate font links when fonts are available for the
current locale and manual font links are not in place.

You could do the same with font replacements. You could have Wine search for
font in compatible encoding, and possibly have a list of preferred fonts that
is configured in registry and can be updated by distributors and users.

If tagging the registry entries as volatile inside wine is too difficult you
can just write the settings twice - once in the standard location and once in
some location like
HKLM/Software/Wine/Autogenerated/path/to/autogenerated/value. That way you will
know if the entry in system registry matches the last autogenerated entry. As a
hint these should be then set to empty when a value would be autogenerated but
is set already.

Note that on Windows the font links are autogenerated and probably overwritten
on locale change but there you do not have to deal with picking different
fonts, the fonts are hardcoded. Wine has to do differently here (eg. pick up
font changes).

Font substitutions should not be touched by wine. They are standard part of
Windows registry that is only configured by user or installation programs. It
might be useful to have per-application font substitutions but that can be
solved by installing problematic applications in separate prefix, the same as
applications that require specific libraries, etc.
