Dear Javier,

If it is not available, it will try to use Tibeta Machine Uni... if it cannot find it either, it will use Wagdi29... and so on. CTL_TEXT is the list for the word processor, etc... Can you make a similar block for Tibetan?
I understand the above block. As far as I know, the Unicode Tibetan fonts are only "Tibetan Machine Uni" and "Microsoft Himalaya". They are all based on OpenType.
Is Tibetan Machine Uni an Open Source font?
Yes, Tibetan Machine Uni is an Open Source font and free.
