I examined a dozen of Tamil truetype fonts (in Unicode as opposed to TSCII encoding)
and none of them has U+0B82. TSCII(glyph encoding widely used even now) doesn't
have U+0B82 (see http://www.tamil.net/tscii/faq5.html), which can indicate that
U+0B82 is not used very often if used at all. In addition to U+0B82,
11 of 12 TTFs (included in Mandrake Linux 9.1:
) don't have Tamil digits and numbers (U+0BE7 - U+0BF2). Some fonts lack
only a couple while others don't have any digits/numbers. Perhaps, most Tamil
speakers prefers Western-style digits (well, they're originated from India
as you know well) to traditional Tamil digits.
Given the situation of current fonts in circulation, U+0B82 and [U+0BE7 - U+0BF2]
may as well be removed from ta.orth. Otherwise, none of fonts in Mandrake Linux 9.1
(also used by other Linux/Unix users) would be recognized as supporting Tamil.
I found this problem after adding 'ta' font preference option to Mozilla
(see <http://bugzilla.mozilla.org/show_bug.cgi?id=204039>. The patch uploaded
there doesn't have font-pref change, yet.).
I asked a native Tamil speakers (Manmathan Kumarathurai : mannan daimi au dk)
about those characters
and was told that I'm right. Below is his response to my query:
You are right. These characters af very rarely used thats why the font
developers didn't use time to create them. They aren't part of the widely used
tscii fonts either.
Thanks for the updates.
