How to display Thai text correctly

[bthoven]

Hi,

I'm using Nokia E50 with latest firmware 7.13 and Isilo 4.33 trial.
I use IsiloX to convert the following Thai website:

http://www.pocketpcthai.com/matichon/

Isilo on my Palm can display Thai characters correctly; whilst Symbian 3rd on my Nokia E50 display unreadable character.

I also try Unicode when using Isilox to convert it; both my Palm and my Nokia cannot show it correctly.

I'm not sure what should I do to make it readable on my Nokia.

Thanks in advance.
