Great! I will send them in two different bug reports.

I think we should also warn users that if they are trying to change the tamil font in their init.el, they should use codepoints instead of the script name,
in the (set-fontset-font) function, because if their font does not support the supplement characters, they will once more be displayed as "tofu".

Where should I write this warning?
