Arundina fonts [0] were created under SIPA's initiation, aiming at Bitstream
Vera [1] / Dejavu [2] compatibility. They were then further modified by TLWG
for certain aspects:
* 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. We attempt to fullfill OpenType requirements for
Thai fonts[3], according to our drafted spec [4]. However, as many
applications, including MacOS before Leopard and Adobe CS2, 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.
