> Also, please help me with another problem, I cannot get Emacs to display tamil supplement characters.
With which font?
Thank you for asking the question, I had assumed that it was the Noto Sans Tamil font, which displayed the supplement characters, but it was actually Noto Sans Tamil Supplement.
And what do you mean by "I cannot"? what happens if
you try?
When typed in Emacs they are displayed as "Tofu" characters i.e. Rectangular Boxes with codepoint inside.
Does the font you use support those characters? Does it support Tamil
in general?
Yes the font supports the supplement characters, but does not support Tamil in general.
> I even added a separate tamil-supplement script to (script-representative-chars) but nothing worked.
There's no tamil-supplement script, though.
Unicode defines one, but AFAIK Emacs removes the "supplement" word from these characters. I think it is defined in admin/unidata/blocks.awk
