Description Pravin Satpute 2010-08-16 08:27:32 UTC 
If character belongs to multiple script, its script get declared as G_UNICODE_SCRIPT_INHERITED, so it inherits script property of previous character.

so pango is doing this well, but when such characters come alone pango is not rendering them properly, other rendering engine i.e qt and icu doing this proper

example: U+0951. U+0952, U+0301 and all character declared as script inherit in http://www.unicode.org/Public/UNIDATA/Scripts.txt


i was initially thinking that this problem in from glib2, i.e it is not returning proper script for U+0951, but i had discussion for same in Unicode mailing list as well

see http://www.unicode.org/mail-arch/unicode-ml/y2010-m08/0148.html
Comment 1 Pravin Satpute 2010-08-16 08:30:24 UTC 
U+0951, U+0301 should render with dotted circle.

if you tell me what kind of solution you expects for this, i will give you patch

presently there are total 80 code-point in unicode with inherits property
Comment 2 Behdad Esfahbod 2012-08-25 17:56:54 UTC 
Roozbeh, any idea why U+0951 is not in ScriptExtensions.txt?  Can you do a review of ScriptExtensions.txt and propose additions?  Now that HarfBuzz is merged, we should switch to using that file soon.
