Language preferences set via GUI do not apply to Flatpak QT apps

[Sadia2000]

I do not know whether this is an issue of a mistaken setting on my end or is it a real bug on the developers' end hence I am asking this firstly to the community.

Hi there!
I have been seeing an issue with apps that use the QT framework where the language preference settings are not properly applied and they instead seem to be taking that setting from the locale.

Example 1

as you can see here, FreeCAD is using a language chosen based on my location (Bengali-Bangladesh) and hence is rendering the numeric values in Bengali. This is not supposed to happen.

Example 2

in this case, Kdenlive is using English numeric values for most of the page. However, for certain regions (RGB Parade- Paint Mode- Green 2) it is rendering using my default language based on my locale (Bengali-Bangladesh) while I have explicitly set it my language preference as English and not Bengali. These are present in all apps using the QT/KDE framework instead of GTK framework and only on Flatpak apps so I think this could be a bug with the flatpak integration with the languages framework on Linux Mint.

you can see my preferences set here in the default "Languages" GUI. Would appreciate any help and clarification!

Also in case anyone needs my setup info for this (I doubt you would) I am providing it here:

It is because the "Region" setting as shown in your screenshot contains not just "currency" but also "Numbers", and the 2 software examples are applying that "Numbers" regional setting.

The actual files that the "Languages" GUI modifies are:
/etc/default/locale
/etc/locale.conf
~/.dmrc
~/.pam_environment
~/.xsessionrc

You can edit them manually to fine tune the language settings.

p.s. The above files don't always exist. For example, in my computer, there is only /etc/default/locale

Also, thanks for helping me out. I set my Numeric values to en_US.UTF-8 and they are working perfectly fine in KDE applications. Thanks a lot. :D

For most locales, the number setting only affect which character is used for decimal place and also how to handle thousand separators etc. They don't mess with the 0-9. They don't replace them with local language alphabets. I wonder how schools in Bangladesh teach Math? Do they use the modern international standard number characters or do they use their local number characters?

I guess the GUI interface split out the "Time format" because there are enough demand (including the devs themselves) who want a time format different from the Language/Region default. We will need a new feature request for your locale issue.

[Sadia2000]

In Bangladesh, we use Bengali numerals in schools, and use the Indian Decimal System for the thousand separator. However, in official environments (like office documents, accounts, tax files) we use the typical international standard number characters. So yeah.

Hmm, I might look into adding a new feature request then. However, I am confused as to where should this feature request be applied to. Does it go to the Cinnamon Desktop Environment or does it apply to some other repository.

Just open a new post (category: idea) in this discussion board, perhaps make a reference to this thread.

Aight, thanks.
