Hi
Interested to know if you have had any response on this or what you did in Thailand. i may need to rollout a site in Thailand and would be interested to know what is available. We run JDE 8.11
It describes an experiment I did to enable Thai text printing for UBEs.
If you need the actual interface to be displayed in Thai you could potentially add vocabulary overrides in Thai. That would be a massive effort to translate everything. There would also be parts of the interface such as the toolbar buttons that couldn't be translated as the language translation for those components are delivered as part of the runtime engine (tool release).
