[scribus] Thai support

[Václav Šmilauer]

Hi folks,

I am working on a flyer which will have one paragraph in Thai. I've had 
the text prepared by someone who can read/write Thai (I can barely read 
the letters). The text appears when I use specific font (Noto Sans Thai 
Regular), but only thai characters; there are also latin (arabic) 
numerals intermixed, which appear as squares. I thought using a 
unicode-aware font such as Arial will just do the job no problem but 
there no thai appears whatsoever.

Someone has an experience with Thai in Scribus?

Cheers!

Vaclav
