Re: [I18n]Re: Thai XIM
Hi,
Excited to hear about mlterm. I'll try it soon. :)
Regarding the Thai XIM, the input method is just one-by-one character
(no sophisticated thing like CJK), plus input sequence check, whose
strictness can be adjusted using XMODIFIERS, as stated in my mentioned
page. It would be great if mlterm also provides the string conversion
callback, so that the XIM can handle the context-sensitive cases.
Regarding tis620 fontsets below...

I think the "negative expansion" is something unrelated to the encoding
fields in XLFD. Rather, it should be distinguished using the XLFD spacing
field: proportional/monospace/charcell. The -p- fonts are allowed
to have negative expand, while the -m- and -c- fonts are not. (Well,
I know there exist Thai fonts of -m- or -c- categories that still
have negative offsets. That's not the right thing. We try to fade out
the adoption of such hack soon.)
I think xterm and emacs approaches are interesting. They rely on -c-
fonts in rendering Thai on the screen matrix. And xiterm+thai should
be fixed somehow to follow this, so that the fake monospace fonts can
become deprecated.
For the time being, we can rely on tis620-0 fonts provided by ETL.
They are true -c- fonts provided for emacs. :)
Regards,
-Thep.
