That's a kdelibs (KatePart) or Qt bug, kde-l10n is just translations.

It looks clearly valid, so changing to ASSIGNED, but I'm not sure how to fix it.

Thanks for reporting this upstream.  Will monitor for a resolution.

Comment 5 Ngo Than 2010-09-27 11:48:10 UTC
it's fixed in qt-4.7.0-3.fc13, http://koji.fedoraproject.org/koji/buildinfo?buildID=196716.
could someone please test it? Thanks

Comment 6 Runa Bhattacharjee 2010-09-27 12:41:44 UTC
Hello,

The rendering for the main conjunct correct. However, there is definitely a problem with the cursoring and the dependent vowel sign gets piled onto the conjunct character:

Thanks.

Comment 7 Pravin Satpute 2010-09-27 14:36:14 UTC
can you check other combinations using U+200D?
it looks to me generic problem with the uses of U+200D 
and deserve different bug and different fix

Comment 8 Runa Bhattacharjee 2010-10-01 09:12:42 UTC
ZWJ is not used for any other combinations. But we may find the same output for combinations with ZWNJ. Would you like me to test out with ZWNJ?

Comment 9 Pravin Satpute 2010-10-04 03:33:11 UTC
i have seen same problem with Devanagari 

i.e 
0915 + 094d + 200d + 0915, even in this combination cursor not get positioned properly

i will report this bug to upstream and work on same

Comment 10 Pravin Satpute 2010-12-09 09:15:29 UTC
any problem in f13, can we close this one?
