Insert Titles in Thai Script

Hi there!

For an international version of one of my films I need to insert THAI TITLES.

I got the translations via Mail.

It is not a special script, when I step in between the letters with the cursor it shows "Helvetica"...

I can open the lines in Mail oder copy them to Pages or Numbers on my Mac.

But I cannot copy the lines to Premiere Title Tool or Photoshop.

I tried all versions of checking the Text buttons in the preferences.

Any Idea???

Thanks,

M
