It looks right in revision 3151.

You are quite right. I didn't test it correctly -- and I didn't understand what exactly you were looking at. There was another table decomposing the character before my recent changes could take effect.

As to the name of the auxiliary glyphs, I agree they weren't good. Now the names are improved. But these are purely for internal use, and my pattern is to prefix auxiliary letters with something identifying their range.

Try the latest SVN.

And see attachment.

In Firefox, with Graphite enabled, I am looking at:

data:text/html;charset=utf8,<span style="font-size:300;font-family:FreeSerif">ꣽ ڽڽڽ ڽ</span>

The first character is the Jain om, which was added to FreeSerif a few weeks ago, to test that I am not using an old cached version of the font. I see four dots above all four positions of the nya. I have not yet tried clearing my font cache.

BTW, Jawi is the name of the alphabet, not the letter, so glyph names like arab_jawi_init are imprecise. Also, since the initial and medial forms look like U+067E, I think you could just use pehinitarabic and pehmediarabic instead of creating new glyphs.

Hi,

Probably you're still seeing an older version from some cache -- this happens in Linux and Windows. Unfortunately, I'm not up to date with installation issues in Mac OS.

Please send us the Unicode text you're looking at.

What program are you using to view the text?

I just built FreeMono from revision 3149 on Mac OS X and U+06BD looks the same as ever, i.e. it has four dots above in all positions.

Hello,

As to the number of dots... this was probably corrected already.

I have now implemented the Unicode passage with substitution tabes in the font.

Thanks!

Hello Anonymous,

Thank you very much. I hadn't seen this. The entry you're referring to, I guess is:

Jawi. U+06BD arabic letter noon with three dots above is used for Jawi, which is Malay written using the Arabic script. Malay users know the character as Jawi Nya. Contrary to what is suggested by its Unicode character name, U+06BD displays with the three dots below the letter pointing downward when it is in the initial or medial position, making it look exactly like the initial and medial forms of U+067E arabic letter peh. This is done to avoid confusion with U+062B arabic letter theh, which appears in words of Arabic origin, and which has the same base letter shapes in initial or medial position, but with three dots above in all positions.

There have been no substitution table entries whatever for this character in Freefont. I will correct that.

U+06BD ARABIC LETTER NOON WITH THREE DOTS ABOVE should have three dots above it pointing upward when final or isolated, and three dots below it pointing downward when initial or medial (http://www.unicode.org/versions/Unicode8.0.0/ch09.pdf#28). FreeSerif gives it four dots above in all positions.
