With which font?

Thank you for asking t= he question, I had assumed that it was the Noto Sans Tamil font, which disp= layed the supplement characters, but it was actually Noto Sans Tamil Supple= ment.

And what do you mean by "I cannot"? what happens if
you try?
=C2=A0
When typed in Emacs they a= re displayed as "Tofu" characters i.e. Rectangular Boxes with cod= epoint inside.

Does the font you use support those characters?=C2=A0 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-representat= ive-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

With which font?=C2=A0 And what do you mean by "I cannot"? what h= appens if
you try?

Does the font you use support those characters?=C2=A0 Does it support Tamil=
in general?

> I also added the tamil supplement codepoints to the tamil composition = rules.

Composition rules have no effect on whether a character is displayed
as a glyph or as "tofu".

> I even added a separate tamil-supplement script to (script-representat= ive-chars) but nothing worked.

There's no tamil-supplement script, though.

=C2=A0 (aref char-script-table #x11fc0) =3D> tamil

See lisp/international/charscript.el, a generated file.

> How can I fix this?

We need first to understand the problem.

P.S. I've moved this discussion out of the bug report to emacs-devel.
