About this project

This project is intended to provide a free and open font family for all current languages and writing systems that use Tai Tham script of Northern Thailand.

The design is inspired by, but not based on, the CR Udom fonts designed by Charin Jamjitt. It has been produced with help from Payap’s Linguistics Institute.

Future plans

These fonts are actively maintained and improved, and recent changes to their development process will enable more frequent releases.

The highest priorities for future additions and enhancements are mainly driven by:

  • New additions to The Unicode Standard
  • Requests from language communities using the fonts
  • Needs of the linguistic and academic community

Please send us your requests using the form on the SIL software website. If you are interested in helping us make the fonts better see the Developer page.
