[Freefont-bugs] sinhala

[Noah Levitt]

 [resending without the patch attached so the moderator
  doesn't need to approve]

Hello,

I discovered that the Sinhala fonts here
http://www.metta.lk/fonts/ are GPL. Click "Download font
from This Server". the .exe is just a zip archive; you can
"unzip" it.

They are not encoded correctly, of course. The sinhala
characters are mapped onto ascii and latin1 code points. 

Using pfaedit, I copied and pasted glyphs from tipita1a.ttf
into FreeSans at the correct code points. I'm attaching a
log of what I put where and some other information.

Unfortunately, the glyphs got screwed up somewhat. I don't
know why. :-( I didn't see this until I had closed and
reopened FreeSans.sfd in pfaedit. I don't know anything
about font editing or pfaedit, so I don't know how to fix it
or do it right.

Attaching a patch. I don't expect it to be applied, since
the glyphs are messed up, but hopefully someone will look at
it and have some advice or be able to do something with it.

 [patch is not attached; it is at

The blanks under "to" mean that the glyph appears to be sinhala, but
there is no character in the unicode chart that looks like it. In some
cases, these appear to be ligatures/precomposed forms.
