Hi, I think the correct solution very much depends on what API is being used to draw the text. 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?
