Installation failing if started from a non-english named folder?

I'm having an issue with NSIS installer related to different language in the file path.
If the installer is started from a folder in Thai language, under Windows XP, it fails.
The message is: "Error launching installer".
Moving the file to an English named folder allows it to be installed.
The problem does not manifest under a different, Windows 7, based machine.

Any ideas/suggestions/solutions?

Thanks in advance!

Try Unicode NSIS.
