Tai Viet script

Tai Viet script

[Andreas Schwab]

language/tai-viet.el contains some encoding errors, apparently the
conversion from the temporary PUA encoding was erroneous.  I've tried to
fix it by comparing the glyphs from the "Unified Thai (20.02.2006)" font
with the "Tai Heritage Pro" font from sil.org, but some characters still
look wrong (ꪁ ꪅ ꪰ) when compared with the version from VietThai-0.9, and
one character () is still encoded in the temporary encoding where I
cannot find a replacement.

Additionally, the composition support was never updated.

Andreas.

As far as I can tell, you applied this patch a few months later, so I'm
closing this bug report now.

The file still contains the bogus character `' which needs to be fixed.

OK; I've reopened the bug report.

Is there a replacement for "" now?  It's been nine years, so perhaps
Unicode (or somebody) has done something.

I don't know about that but at least the documentation of the Tai Viet
script in tai-viet.el needs to be updated: the code points are no longer
from the Private Use Area and a font with that encoding is no longer
available at the URL provided.

I asked on the Unicode mailing list, let's see what that brings.

Btw, I also am not sure the rest of the Tai Viet text there is
correct; for starters, there's no such thing as "the Tai Viet
language": the script is used for several languages.  Likewise with
the greeting text: couldn't verify it with a few similar samples I
found.  (Once we figure all that out, we should add an entry to HELLO
with the same greeting, btw.)

Yes, of course.  But all of those are rather trivial; the problems I
mentioned aren't, at least for me.  When we fix the more serious
problems (or decide we don't know how to do that for now), we will
also fix the ones you point out.

With help of the people on the Unicode mailing list (the most
important contribution was sent to me off-list), I've now fixed all
these issues, and I'm marking this bug done.
