Konsole (KDE) bug.

Thalassius · 12-06-2021, 06:24 AM

Hi!

I'm on a Debian based distro and I stumbled upon this KDE bug:
Konsole can't display non-English characters. It displays semigraphics instead.

My directories use Greek characters, so I have a problem here.

Any known workaround?
(Otherwise I have to try another desktop. I suppose).
TIA!

Only Konsole? Does it mean other terminal emulators display Greek?

From the Common Issues in The Konsole Handbook:

Quote:

Some fonts might be unavailable for usage in Konsole, although they are available in other applications. That doesn't mean there is a bug in Konsole. Konsole requires monospaced fonts to provide the best visual result, so it asks Qt™ to only list monospaced fonts.

Starting with version 16.08 (August 2016), Konsole can be configured to allow selecting any font with the caveat that the display may not be correct.

Setting the font for Konsole is done in
Settings ‣ Edit Current Profile... ‣ Appearance ‣ Select Font...

Also check
Settings ‣ Edit Current Profile... ‣ Advanced ‣ Default character encoding

Indeed, I changed the default font (Hack), with another, that I know for sure it has Greek support.

It has activated the Greek ISO (8859-7) and It can't be changed to Default (none selected). Other ISOs can be selected, but of course they don't help.

PS. Other terminal emulators, working properly (eg. UXterm).
Maybe switching to another one, is the solution.

You should set character encoding to default UTF-8, not to single-byte encodings. What's you locale (LANG)? - should be el_GR.UTF-8. Hack is a unicode font and it does support Greek: https://github.com/source-foundry/Hack

Indeed its el_GR.UTF-8.
Ehm...I tried it through the interface, but it can;t be changed (Probably a bug).
How it can be changed to default UTF-8, not to single-byte encodings?

Indeed! I didn't notice and I changed it to Dejavu, just to be sure.
I rolled back to Hack.

Konsole profiles are stored ~/.local/share/konsole, you probably should be able to change the encoding there. Never tried it myself though.

I can see several options, but it doesn't seem to have a related one.

Well...it seems to be, a Debian bug.
It probably is the 902299.
I don;t know if its a coincidence, but if you look at the post, the problem occurs with Greek alphabet.
Look to the end of the page, for the word "φαρμακεία". (It means pharmacies)

Anyway! I give up. I don't know a way. to fix a Debian stable bug.
I searched for Konsole's alternatives, and I found that these 2, are possibly the best candidates. Both Qt based, they're fitting nicely to the environment:

1) QTerminal (LXQt's terminal, available as a standalone package and 2) Trinity's Konsole (if you willing to add the repository and install the tdebase-trinity package (the base package of TDE)).

THANKS! Bye!!!

The first post in the linked bug report gives a workaround:

Quote:

After some investigation this bug seemed to be triggered by changes made in KDE's System Settings, Regional Settings, Formats, changed the Region from Default "United States - American English (en_US)" to "Nederland - Nederlands (nl_NL)" since I wanted to use the number/date/currency/paper/unit formats of the Netherlands.

Setting it back to default "No change" and re-login and the problem in konsole is gone.

Nope! Didn't help here.
