Re: bug#55745: [PATCH] Add support for the Hanifi Rohingya script

[समीर सिंह Sameer Singh]

This is a sub-optimal solution IMHO.  There will always be cases where
a script is split into multiple Unicode blocks, probably mapped to
different fonts.  AFAICS, the Tamil supplement characters don't
interact typographically with normal Tamil characters, so a two-font
solution in this case is valid.  In case my assumption is invalid you
should submit a bug to the Noto project :-)

I agree it is somewhat sub optimal, but Emacs does not differentiate between supplement and "base" characters, so setting different fonts for both of them does not seem possible.

There also seems to be no font which supports both Tamil and its supplement characters OOTB.
