Description of problem:
It was announced
(https://www.redhat.com/archives/lohit-devel-list/2012-February/msg00011.html)
that the latest 2.5.1 version Lohit fonts support latest Unicode 6.0
characters. Especially Malayalam was also mentioned.
However I find that the Lohit Malayalam 2.5.1 release downloadable from
https://fedorahosted.org/releases/l/o/lohit/lohit-malayalam-ttf-2.5.1.tar.gz
does NOT provide support for 0D4E MALAYALAM LETTER DOT REPH.
As this is one of the three Malayalam characters encoded for Unicode 6.0 (see
http://www.unicode.org/Public/UNIDATA/DerivedAge.txt and search for 0D4E) it
should also be supported.
[The other two characters are provided but 0D3A has a wrong glyph which I have
reported as bug 798870.]
Version-Release number of selected component (if applicable):
2.5.1
Steps to Reproduce:
1. Install Lohit Malayalam 2.5.1 font.
2. Try to use 0D4E MALAYALAM LETTER DOT REPH
Actual results:
This character is not available.
Expected results:
This character was encoded to support the old Malayalam orthography. As such it
should be made available for full Unicode 6.0 (or 6.1) support.
Additional info:
You might need to do some smart font programming to position the dot reph
correctly. Note that this character is a special rendering character (hence the
dotted box around it in the code chart
http://www.unicode.org/charts/PDF/U0D00.pdf).
The special rendering is that it should be placed on top of the character
*following* it. See the original proposal bottom of page 3 and top of page 4.
I think the e-Malayalam OTC font
(http://www.aai.uni-hamburg.de/indtib/INDOLIPI/Malayalam.zip) has pre-composed
glyphs using this character on top of other consonants which might help you in
positioning this character. Note that most often it is found with doubled
consonants (i.e. DOT_REPH + GA + VIRAMA + GA etc) so you will have to be able
to position this character above stacked consonant clusters.
I hope this is sufficient feedback for supporting this character which is
important for old Malayalam orthography.
