Tibetan rendering amiss despite attempts with multiple fonts

[julkamny]

Hello,

First of all thanks for this amazing library, it has helped me achieve things I believed far beyond my ken. I am attempting to output a PDF which contains Tibetan words. For detailed information about the script used to write this language, please take a look at : https://docs.microsoft.com/en-us/typography/script-development/tibetan#examples-of-tibetan. Your help would be greatly appreciated, I have spent many hours crafting my program, it works well and could have interesting educational benefits, this font issue really bogs me down... 🙏🏿

The issue

doc[0].insertTextbox(rect, "རྒྱསྒྲ", fontsize = fontsize, fontname="jomolhari", fontfile = jomolhari_font_path) produces the attached picture, whereas it should produce well, what hopefully you see on your screen : a neatly arranged stack of ར + ག + ཡ (the form of this last consonant changes when it is placed at the bottom of a stack) and a neatly arranged stack of ས + ག + ར. Even གྲ is not properly displayed.

My attempts

• Multiple fonts, at least half a dozen, NotoSansTibetan, Yagpo, TibetanMachineUnicodeFont. The one that seems to work best is Jomolhari.
• I run into the very same issue with Reportlab. This may hint at a problem on my side ? Or a general problem with Tibetan not tied to MuPDF specifically ?

My configuration

• MacBook Air, High Sierra 10.13.6
• PyMuPDF 1.18.12: Python bindings for the MuPDF 1.18.0 library. Version date: 2021-04-10 04:00:00. Built for Python 3.8 on darwin (64-bit).
