Incorrect rendering of U0CAA U0CCA U0CAB U0CCA

Wrong Conjuct combinations are formed for U0CAA+U0CCA, U0CAB+U0CCA, U0CAA+U0CCB, and U0CAB+U0CCB as well.

Version-Release number of selected component (if applicable):
fonts-kannada-2.1.5-3.fc8

How reproducible:
1. Every Time

Steps to Reproduce:
1. Open gnome-character-map.
2. Select U0CAA followed by U0CCA followed by U0CAB followed by U0CCA.

Actual results:
As shown in the attached image

Expected results:

As shown by the following steps:
1. Install http://kannadakasturi.com/font/brhknd.ttf.
2. Open http://kannadakasturi.com/includes/transliterate.asp.
3. Enter the combination poPo.

Additional info:

1. The fonts from http://sourceforge.net/project/showfiles.php?group_id=56358
also show the glyphs like kannadakasturi.com instead of like Lohit Kannada.
2. This is similar to the earlier issue reported here.
3. Using the program from http://gfontview.sourceforge.net/ it is seen that there already are glyphs in the font named U0CAC_U0CCA.pstf [can be renamed to the more appropriate U0CAA_U0CCA.pstf?] and U0CAB_U0CC3.abvs_U0CC0.psts [can be renamed to U0CAB_U0CCA.pstf?] which show the conjuncts like kannadakasturi.com. Only the mappings between the character combinations and the glyphs to be displayed seem to be incorrect.

Hence I assume Lohit Kannada is at fault and not the other fonts.

Comment 7 Rahul Bhalerao 2009-01-13 12:42:10 UTC
The brhknd font mentioned is not a unicode/opentype font. Please provide correct screenshots instead.

Rahul,
The above said rendering is there in Lohit-Kannada also. You can have look at the screen shot attached

Comment 9 Padmanabhan V. K. 2009-01-17 17:56:40 UTC
Please note that there already are glyphs in the font named:
U0CAC_U0CCA.pstf [can be renamed to the more appropriate U0CAA_U0CCA.pstf?],
U0CAB_U0CC3.abvs_U0CC0.psts [can be renamed to U0CAB_U0CCA.pstf?],
U0CAA_U0CCB.pstf, and
U0CAB_U0CCB.pstf,
which show the correct conjuncts. Only some ligature rules in the font should be changed, like in the previous patch.

Comment 10 Shankar Prasad 2009-03-02 07:29:14 UTC
Rahul,

Any updates in this?

Comment 11 Rahul Bhalerao 2009-03-04 05:39:15 UTC

Comment 12 Rahul Bhalerao 2009-03-05 14:23:11 UTC
Fixed in lohit-fonts-2.3.8.
