non-free
This section lists candidates for the non-free section of the archive. Do not add fonts that you know we cannot distribute.
Siddhanta by Mihail Bayaryn, covering several blocks not available at all in debian at the moment: Devanagari extended, Common Indic number forms and Vedic extensions; the font is using the CC-by-NC-ND 3.0 license, but the author has previously made fonts available with GPL; as other projects (Fedora, SIL) are working on extending their Devanagari fonts the need for this non-free font may be outwaited
