Uniscribe functionality, especially on supporting devanagari, would require Harfbuzz, besides and beyond fontconfig and freetype. Is Harfbuzz an (optional?) dependency of wine these days?

Also, the fallbacks are defined in this table, iirc. https://gitlab.winehq.org/wine/wine/-/blob/master/dlls/gdi32/uniscribe/usp10... -- Bernhard Am So., 5.

Hi, I can still reproduce this issue on the latest master at the time of writing this.
For example open: wine notepad and type something like: देवनागरी Instead of the program falling back to an appropriate font, "tofu" blocks are shown instead.
Now, in ./dlls/gdi32/uniscribe/usp10.c I can see a function named: "find_fallback_font" which looks for a fallback font under Software\Wine\Uniscribe\Fallback in HKEY_CURRENT_USER. But I did not find this entry populated at all.
My solution is: Define a table which has a representative char for each script, now when a new wine environment is being created, query the system using FontConfig to find fonts which contains the representative chars and then populate the registry entry.
How does this sound? I have a rough working version right now, should I send a patch or is something missing in my current approach?
