Unfortunatly the Thai lanmguage in Mozilla is way way behind the other ones. M14 being the most recent Mozilla that has Thai support:

Sometimes on Windows it is possible to use a special Thai font to get the Thai character set:

I imagine that if the font is translated to whatever Linux handles, that it might work there as well?

Or:

To make X window application displays Thai font, you should run the application with -fn option. For example,

%xedit -fn thai8x16

Note that thai8x16 is just a one of Thai font names. You can see all available fonts by command xlfonts. If you don't want to fill -fn option every time you run application. You should set Thai font in your ~/.Xdefaults or ~/.Xresources like this
XTerm*font: thai8x16

I imagine this changes the default font to the Thai font to trick X into using the Thai Font?

Linux or Unix Thai Fonts:

Not real Thai language support, but the Font should be able to display Thai characters.
