Created attachment 119619 [details] Russian folders with different first letters in single 'A' group All files and folders with cyrillic names are placed in latin 'A' group. They're expected to be in groups according to their first letter. See screenshot with russian names for example. STEPS TO REPRODUCE 1. Create some files with cyrillic names 2. Select View -> Sort By -> Names 3. Enable View -> Show in groups
Indeed the latin letter range 'A'...'Z' is hardcoded, see https://cgit.kde.org/dolphin.git/tree/src/kitemviews/kfileitemmodel.cpp#n1899 We could add (at least) greek and cyrillic letter ranges.
Created attachment 120098 [details] Grouping works fine with some non-latin chars Sorry, forgot to mention that not all non-latin symbols maps to latin A..Z. That's why I only wrote about cyrillic names. Greek symbols works fine for me, also chinese and japanese, for example.
It turned out that the problem depends on the language. For example, grouping works fine with English (GB and US) and German, but not with Russian (ru_RU.UTF-8). Run dolphin with LANGUAGE variable to test: > LANGUAGE="en_US.UTF-8" dolphin
For some reason QCollator thinks that cyrillic(or at least russian) symbols are less than latin characters, while the code seems to be written with the assumption than they are bigger. I made a patch to consider such case. https://phabricator.kde.org/D22303
