I have been trying to localize Bangla (Bangladesh) for wine. When I ran my
changes, I saw the text's were broken up due to conjoined letters not being
properly handled (য-ফলা,ব-ফলা,র-ফলা). A screenshot of it and a log are given.

Also for getting Bengali fonts to work on macOS, I needed to do the following:
1. Install some Bengali font (e.g SutonnyOMJ)
2. Add to regedit HKLM\Software\Microsoft\Windows
NT\CurrentVersion\FontLink\SystemLink Tahoma (e.g SutonnyOMJ
Regular.ttf,SutonnyOMJ)
# These are done because, at least on my OS version, bn_BD is not given.
3. cp /usr/share/locale/en_US.UTF-8 ~/.locale/bn_BD.UTF-8
4. export PATH_LOCALE=~/.locale

5. LANG=bn_BD.UTF-8 wine ...

Screenshot Bengali without(left)/with(right) winetricks fonts installed for

Bottom right Bengali look correct for emacs.exe? 

Via all winetricks fonts installed for Emacs zoom/scaling bug:

`য-ফলা,ব-ফলা,র-ফলা`
This is the names/concept of the subjoined letters, not the letters themselves.
For a proper example of this: সংযুক্ত শব্দ
Also you're using an external program, i don't know what mechanism it uses, but
I don't think it applies to wine internal programs (which I am translating
for).

I tried doing winetricks allfonts, and that didn't change anything (even after
reverting FontLink registry change; well that just causes boxes to appear on
text, with or without winetricks allfonts)

Thanks for clarifying.  I'm not fluent so just going on basic pattern matching.

Do you have a separate Bengali po file you're translating because it seems to
be missing unless I missed it.  Changing locale seems to be working for other
languages like German which has a po file.

I checked every font available via winetricks not just allfonts checkbox. 
Unclear if that helps.
