Re: [users] Konsole freeze on (UTF?) characters - Workaround

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 

TLDR: downgrade libtqt3-mt to Fedora32 version

from: libtqt3-mt-3.5.0-14.0.9_1.fc33.x86_64

to: libtqt3-mt-3.5.0-14.0.9_1.fc32.x86_64

-----

Setting it to UTF8 does not help, neither does any other encoding or font. Nor does it matter what environment variable I have set (LC_*, LANG). Looks like to problem with the actual font rendering, maybe something that was changed in Fedora 33 (in TDE for f33).

I have tried a new installs of Fedora32, Fedora31 and 33 and it works there without a problem with the f32 repo. As soon as I upgrade to f33 tde konsole starts freezing.

This is a tail of strace -ff of the freeze:

Hi. Since upgrading to fedora 33 my konsole began freezing when it
encounters non-ascii characters. I've tried different fonts and even
installed TDE on a new fedora VM, still freezes.

For example : cat /usr/share/applications/*

	In Konsole, open Settings => Encoding and make sure that UTF8 (near the bottom) is selected; then go to Settings => Save as Default.
	You might also need to export environment variable LANG='xx_XX.UTF-8' (mine is en_US.UTF-8) if it's not set appropriately.
