Broken character encoding in window titles for programs opened by KMail #45

Basic information

TDE version: R14.0.9
Distribution: Debian Buster
Hardware: amd64

Description

I just discovered a weird problem with character encoding handling. I won't be surprised if this isn't KMail-specific.

Steps to reproduce

Rename KPDF menu entry to "KPDF ąęśźćżńł"
Launch KPDF from TDE menu. Notice that Polish diacritic signs are displayed correctly (first screenshot)
Launch KMail
Select an email that contains a PDF attachement
Click on the attachement and select "Open in KPDF ąęśźćżńł"
Notice that Polish signs in the window title are now completely broken (second screenshot)

This happens on TDE set to Polish language but the OS itself is set British English locale:

$ locale
LANG=en_GB.UTF-8
LANGUAGE=en_GB:en
LC_CTYPE="en_GB.UTF-8"
LC_NUMERIC="en_GB.UTF-8"
LC_TIME="en_GB.UTF-8"
LC_COLLATE="en_GB.UTF-8"
LC_MONETARY="en_GB.UTF-8"
LC_MESSAGES="en_GB.UTF-8"
LC_PAPER="en_GB.UTF-8"
LC_NAME="en_GB.UTF-8"
LC_ADDRESS="en_GB.UTF-8"
LC_TELEPHONE="en_GB.UTF-8"
LC_MEASUREMENT="en_GB.UTF-8"
LC_IDENTIFICATION="en_GB.UTF-8"
LC_ALL=

I wonder whether this is reproducible on TDE set to English language.

Hi Janek,

just wondering if you have tried switching TDE to English and reproduce the bug, so we can have more info available.
