Fixed. Kleopatra and the GnuPG System configuration and error messages coming from GnuPG should now always use the configured Windows display language regardless of the Preferred languages or the Regional format. (GnuPG on the command line will still use the Regional format.)

The language settings of Windows have strange influence on Kleopatra and GnuPG.

Right, gpg CLI output depends on it, too.

Notes to self:

• On Windows, libgpg-error's gettext replacement uses the value of LC_ALL, LC_MESSAGE, or LANG (in this order) if set. Otherwise, it uses Windows's GetThreadLocale. (gnupg should probably use the MUI API instead.)
• We should probably force Qt's/KDE's language on gnupg by setting LANG.

I have no idea how Qt/KDE and how gettext (resp. gnupg's replacement of gettext for Windows) react to Windows's "regional format" setting. It seems that Qt/KDE correctly use English despite German regional format while gnupg uses German.

The screenshots were made with

• ISO: EnglishInternational
• Windows Language: English (United Kingdom) - note: i installed English (United States), but can't select it
• Country or Region: German
• Regional Format: German

For such language tickets please give more information. What are your language settings? Not only in Kleo, the system language settings, too.

That's not surprising. The fix was made after GpgOL 2.6.7. And gpg4win-5.0.0-beta395 still seems to include GpgOL 2.6.6 only.

Looks good to me on gpg4win-5.0.0-beta395 @ win11

Issue is still present in gpg4win-5.0.0-beta395 @ win11:

This happens only in the 64-bit builds, i.e. with Gpg4win 5.

Thanks. Will go into 2.4.9 to be released soon.

All applied.

The umlauts are ok again!

I have reverted the commit mentioned by Carl and another text codec related commit for the Qt 5 builds. This will hopefully fix the broken umlauts in the progress messages.

This might be caused by https://git.gnupg.org/cgi-bin/gitweb.cgi?p=gpg4win-tools.git;a=commit;h=30b5736a97d884452c9ad8c713600326ee06a7c3

Thanks! please consider adding it to 2.2 and master as well. I suspect it's more outdated than it would be if it had been shipping in the upstream tarball.

Pretty outdated, but I add it nevertheless to 2.4
s/gnupg-2.4/po/nl.po: 1320 translated messages, 625 fuzzy translations, 268 untranslated messages.

Thanks for your work. I applied it to Gpgex.

Will do. Thank you very much.
