- Latin glyph size compatiblity. That is, Latin glyphs should have equal size with those from Western fonts at the same point size, so that it would not require users to scale fonts when using them together in the same documents.
- OpenType conformance. Similar to the Fonts-TLWG project we have done, we attempt to fullfill OpenType requirements for Thai fonts, according to our drafted spec. However, as many applications, including MacOS before Leopard and Adobe before CS3, do not support the Thai-specific features well, the 'liga' GSUB hack developed by the original author is still retained for the time being.
We use FontForge as development tool. You need it to generate fonts from the downloaded source.
See the Font Samples page.
Since the fonts are based on Bitstream Vera, they are therefore licensed under Bitstream license.
You can get the original fonts at SIPA's site
Fonts-SIPA-Arundina is currently maintained at GitHub.
We use thai-linux-foss-devel mailing list as our communication channel for Fonts-SIPA-Arundina development.
