Hi Werner,
It looks like I have found what's wrong with cjk-enc.el :-). Here is the
important part in cjk-encode - I got this to work with both emacs 22 and emacs
23, and *just for Thai-tis620*, okay:

=======================================
The problem, in a nutshell, is that "char-charset" starts to return "unicode"
for every non-ascii character in emacs 23, over "chinese-big5-1", etc.
("charset-list" has expanded and nearly doubled in size).
I can see two ways out - either you set the charset priorities and put
thai/chinese/korean first, before identifying bytes as unicode, or limit the
"char-charset" search to a list of your choice and excluding "unicode" among
the
list, in the 2nd chunk above (and probably rework a little bit of the logic
further below in cjk-encode).
I left some debug code above for you to experiment with, to come up with the
correct list in either the first solution or the 2nd solution outlined. I tried
copying the list from cjk-format-spec-table or cjk-encode but neither works
very
well (I think iso8859-x probably shouldn't be there, or in a different order)
so
I think I'll stop - for now, it working for Thai is good enough for me.
Oh just for some geek credit, if you feel like mentioning my name
(e.g. http://debbugs.gnu.org/cgi/bugreport.cgi?bug=8108), that's fine by me :-).
(my sourceforge address still works and is the preferred address for any public
listings...)
