Hi! Found a problem in Dolphin 17.12.3. If a full file name contains international characters ('/home/ДЖЕНС/photos/me.png'), the cache subsystem of the thumbnails does not work - the cache file '<MD5>.png' is created in the '/home/<user>/.cache/thumbnails/', but when I re-access the folder, Dolphin can not find it. As a result, a thumbnail image is recreated each time, and not read from the cache. For files that contain only ASCII characters in their full name ('/home/jens/photos/me.png'), the caching works fine. Ubuntu file manager does not have this problem.

The thumbnails are made by the kio, not the Dolphin. The kio-extras has the imagethumbnailer. Testing with the Arch Linux and kio-extras 17.12.3. Making: '/media/sda2/ДЖЕНС/Test image.png' The $HOME/.cache/thumbnails/large/ has 6e98d381fb094a267833e60e670dc1dd.png When executing in the $HOME/.cache/thumbnails/large/ command: 'exiftool 6e98d381fb094a267833e60e670dc1dd.png' There is correct Thumb URI: file:///media/sda2/ДЖЕНС/Test image.png Full output: https://pastebin.com/vZvtsHzF Could you check your thumbnail metadata ?

Are you using the UTF-8 encoding ? Could you add the 'locale' command output ?

I can't reproduce this BUT I'm not using the Neon or dont't have the cyrillic keyboard I'm just turning the status as unconfirmed.
OK thanks! Very strange: I tried to reproduce the error on neon-devedition-gitstable-20180320-1047-amd64 (English) in Live CD mode - the error is reproduced. On kubuntu-17.10.1-desktop-amd64 (English) in Live CD mode - NOT reproduced, everything is OK! It is necessary to put the old kubuntu - I hope, updates will not spoil it ...)
Likely fixed by https://invent.kde.org/frameworks/kio/-/commit/371e523f5d7ee0e37934135db6499eff3b976162
