            Bug ID: 60087
           Summary: GDI+ cannot find a private font family by its reported
                    name
           Product: Wine
           Version: 11.14
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: gdiplus

When running Adobe Premiere Pro 2025 25.5 with Wine 11.14-14-g84fe968b936,
startup fails with the following message after the Adobe Clean fonts have been
installed and registered:

    unable to load operating system font.
    GDI Status: FontFamilyNotFound
    Font: Adobe Clean Style

The same behavior can be reproduced without Adobe using the existing long font
name resource in the GDI+ font tests. After a private font is loaded,
`GdipGetFamilyName()` reports its family name, but passing that name and the
same collection to `GdipCreateFontFamilyFromName()` returns
`FontFamilyNotFound`.

The reduced trace shows:

    trace:gdiplus:GdipGetFamilyName 0000000000837220, 000000000031F9F0, 0
    trace:gdiplus:GdipCreateFontFamilyFromName
L"wine_3_this_is_a_very_long_name", 0000000000823FC0 000000000031F9E0
    trace:font:font_EnumFonts facename = L"wine_3_this_is_a_very_long_name"
charset 1
    font.c:124: Test failed: GdipCreateFontFamilyFromName failed: 14

`GdipCreateFontFamilyFromName()` currently asks GDI to enumerate the requested
name and compares the resulting `LOGFONTW.lfFaceName` with the family names
stored in the private collection:

    if (!wcsicmp(lf.lfFaceName,
            collection->FontFamilies[i]->FamilyName))

The name returned by GDI can differ from the name stored and reported by GDI+.
This causes a valid family in the supplied private collection to be rejected.

Steps to reproduce:

1. Add a font with a long family name to a private GDI+ font collection.
2. Obtain its name with `GdipGetFamilyName()`.
3. Pass that name and the same collection to `GdipCreateFontFamilyFromName()`.
4. Observe that unpatched Wine returns `FontFamilyNotFound` with status 14.

The candidate patch first compares the requested name with the family names in
the supplied collection. It retains the existing comparison with the name
returned by GDI as a fallback. The patch also extends `test_long_name()` to
exercise this lookup.

The new check fails on unpatched Wine in both 32 bit and 64 bit tests:

    font.c:124: Test failed: GdipCreateFontFamilyFromName failed: 14

The check passes with the candidate patch in both architectures. The complete
local font test still has four unrelated metric failures at `font.c:452`, which
occur with both the patched and unpatched builds.

Application verification confirms that the patch removes the Adobe Clean
`FontFamilyNotFound` startup failure. Native Windows test results have not been
tested.
