Need help for language files with UTF-8

[jppp]

Hello,

I've installed the zen cart v. 1.3.7 and used it in Thai. Everything works fine. I've set up my mysql database using UTF-8 and defined my pages by changing character set into 'CHARSET', 'UTF-8'. However, if I tried to change NAVBAR_TITLE or HEADING_TITLE in language files (includes/languages/thai/...), they can't be read. They comes out in unreadable texts. Anyone can help me with this...

Thanks,
JPPP

UTF-8 is most likely not what you want if using a foreign language

If I want to use in Thai. What CHARSET should I use?

I just searched Google for "Thai Charset" and these results came up ... not sure if it helps:
