Hi Yamin,

Have you tested this font in OOo on Linux?

We developed support for Tibetan script in the ICU library a couple of years ago (working in Bhutan). This library is the one that gives support to complex scripts in OpenOffice. ICU, and the rendering engine support standard unicode. It would consider any character outside of the Tibetan range as a foreign character that might not be combined with other tibetan characters. If you have combination characters with a code-point in the private-use area that do not have any other characters in the same cluster, this might it might work (same as if you added a Latin character in the middle of a word, it will break the text run, but it will work). Nevertheless, if you have a combination of characters that have been given a code-point in the private area, this combination will not be able to further combine with tibetan dependent vowels or any other sign... you would get a dotted circle as the base for the vowel.

I undertand from your message that if only characters in this block are used, they will also be stacked and rendered correctly... this would be displayed correctly in OOo in Linux.

Cheers,

Javier

Dear Javier,


Yes, I have introduced the Tibetan font "Jomolhari" which supports Tibetan
Unicode standard as well as extend-A character set standard which includes
hundreds of pre-composed Tibetan characters.


Hi Yanmin,

Are these extra characters in the font ligatures? or are they code-points
in the private usage range of Unicode?


Jomohari is an excellent OpenType font which include all CTL features for
Tibetan. So, the Tibetan Unicode text can be presented correctly using
Jomohari. Tibetan Extend-A character set standard which includes
frequently-used pre-composed glyphs takes the private usage range of Unicode
(U+F300-U+F8FF). Jomohari also comprises the Tibetan characters of Extend-A.

Regards,
Yanmin
