Created attachment 155648 [details] Lowercase and uppercase t with Comma below look like they have a Cedilla below SUMMARY *** Kate shows the some characters with the wrong diacritics for Romanian language *** STEPS TO REPRODUCE 1. Add a Romanian layout with a Romanian (standard) variant 2. Open Kate 3. On row 1, type: ș Ș 4. On row 2, type: ț Ț OBSERVED RESULT The lowercase and uppercase "ț" character has something that looks like a Cedilla below. https://en.wikipedia.org/wiki/Cedilla Like this: https://unicodeplus.com/U+0163 https://unicodeplus.com/U+0162 EXPECTED RESULT The lowercase and uppercase "ț" character should should use something that looks like a Comma below, similar to the "ș" character. Like this: https://unicodeplus.com/U+021B https://unicodeplus.com/U+021A SOFTWARE/OS VERSIONS Linux/KDE Plasma: KDE Plasma Version: 5.26.90 KDE Frameworks Version: 5.103.0 Qt Version: 5.15.8 ADDITIONAL INFORMATION Tested on latest version of KDE Neon (neon-testing-20230124-0252.iso), fully updated, on Wayland. Romanian keyboard layout: https://en.wikipedia.org/wiki/Romanian_keyboard_layout The problem seems to be only visual. I copied and pasted the typed characters and they are indeed t with comma below as they should, confirmed by Unicode testing sites and by looking correctly in Firefox.
Changing to another font, like Monospace, Courier 10 Pitch, DejaVu Sans Mono, Liberation Mono, Nimbus Mono PS, Noto Mono, Noto Sans SignWritinng fixes the problem the problem. So it seems that only the default Hack font has this problem with this character in both lowercase and uppercase versions.
Seems like a bug in the Hack font, not a bug in Kate. I'd recommend you report it here: https://github.com/source-foundry/Hack/issues
