Description Feufochmar 2015-04-06 21:41:39 UTC 
When displaying unicode files containing IPA characters with combining diacritics in Kate, the diacritics are incorrectly placed. They are placed on the character after the combining diacritic and not on the character before the diacritic.

Reproducible: Always

Steps to Reproduce:
1. Open Kate
2. Copy and paste the following characters in the editor: ɐ̃w
(LATIN SMALL LETTER TURNED A, COMBINING TILDE, LATIN SMALL LETTER W)

Actual Results:  
The tilde is located above the character "w".

Expected Results:  
The tilde should be placed above the character "ɐ"

I'm using DejaVu Sans Mono as monospaced font.
There is no problem with KCharSelect 1.11 (KDE 4.14.6) when displaying this text with this font. However, I see the same problem in Konsole (v3.0.1, KDE framework 5.8.0).
Comment 1 Louis Moureaux 2015-05-24 00:01:12 UTC 
I can reproduce with DejaVu Sans Mono ; the tilde is only slightly displaced with Oxygen Mono. This looks like a problem in Qt, because other Qt 5 applications are affected.
Comment 2 Christoph Cullmann 2015-10-09 08:07:07 UTC 
Please report that upstream to the qt proejct if that still happens with current Qt versions, Kate can't fix that.
