Unsupported locale setting on module import for Norwegian locale

[Lore-Gaviano]

Desktop (please complete the following information):

ttkbootstrap Version = 1.10.1 OS: Windows 11 Pro

Describe the bug

When working on a PC with Norwegian locale, DatePickerDialog throws a "local.Error", failing the import of ttkboostrap. Norwegian locale contains non-ASCII characters "å", which is not accepted in setting the locale in line 566 of \ttkbootstrap\dialogs\dialogs.py".

To Reproduce

Set computer region to Norway and import ttkbootstrap.

Expected behavior

I'm not sure if my response will help you, but I've had a similar error in the past that had the same root cause as your error, which, in this case, is located in the 'dialogs.py' file at line 566. I believe that if you adapt the solution from that issue to yours, it may resolve your problem.

Based on the given link, do something like this:

set_locale_to_posix()
# Here would be all the code that uses formatting according to your preferred locale
# ....
set_locale_to_system_default()

I recommend creating functions that handle this entire process automatically, avoiding code repetition. Try doing this and then provide some feedback. Good luck! :smile_cat:

[Lore-Gaviano]

Thank you for your answer, but I believe the solution may not be applicable, because the error occurs exactly the same.

import locale 
def set_locale_to_posix():
    locale.setlocale(locale.LC_ALL, "C")

def set_locale_to_system_default():
    # This part was taken from line 566 of the "dialogs.py" file present in the "ttkbootstrap" library.
    locale.setlocale(locale.LC_ALL, locale.setlocale(locale.LC_TIME, "nb_NO"))

set_locale_to_posix()
import ttkbootstrap as ttk
set_locale_to_system_default()

The problem comes from the fact that locale.setlocale(locale.LC_TIME, "")) in line 566 returns "('Norwegian Bokmål_Norway', '1252')" and the letter "å" can't be passed to locale.setlocale(locale.LC_ALL, "Norwegian Bokmål_Norway").

I have been looking into changing the default locale to something of my choice from python, to import ttkbootstrap and reset it to Norwegian at the end of the script.

I don't really have any operation to do with a particular date format, I just need to import the model, but that is when the error is raised.

I tried and tried and figure out, solve it just in a simple way:

1. Just open up the dialogs.py in folder: "C:\Users\"user"\AppData\Local\Programs\Python\Python312\Lib\site-packages\ttkbootstrap\dialogs\dialogs.py", line 566

2. Overwrite this line locale.setlocale(locale.LC_ALL, locale.setlocale(locale.LC_TIME, "")) with "tr_TR.utf8" (but you can overwrite as default with "en_EN.utf8") locale.setlocale(locale.LC_ALL, locale.setlocale(locale.LC_TIME, "tr_TR.utf8"))

and everything runs without any problem.

@Neoakay005's solution works. Thank you very much. However in case I wanna share my project, the receivers would need to execute the same changes in their own local package. This could potentially represent an annoyance. Perhaps it could be worth making a similar change in the repo too. Thanks!

Perhaps it could be worth making a similar change in the repo too.

Then please reopen this issue. Although there isn't much activity on the project lately, it's better to leave unresolved issues open.

import locale 
locale.setlocale(locale.LC_ALL, "C")

Running this at the start of my App helped me fixing "???" characters instead of months (It was probably trying to load Cyrillic)

Did anyone find a solutions for this? I'm also on nb_NO as all potential users of the app.

For Norwegians do as Neoakay005 suggested. But instead of changing the line to: locale.setlocale(locale.LC_ALL, locale.setlocale(locale.LC_TIME, "tr_TR.utf8"))

change it to this: locale.setlocale(locale.LC_ALL, locale.setlocale(locale.LC_TIME, "no_NO"))

At least that worked for me.
