`locale.windows_locale`: Incorrect Windows locale for Cambodian

[seanbudd]

Bug report

Bug description:

According to the Windows spec, the locale identifier for Cambodian (0x0453/1107) should be "km-KH"

Sources:

• https://learn.microsoft.com/en-us/openspecs/windows_protocols/ms-lcid/70feba9f-294e-491e-b6eb-56532684c37f
• https://ss64.com/locale.html

Currently locale.windows_locale[1107] == "kh_KH" incorrectly.
https://github.com/python/cpython/blob/3.12/Lib/locale.py#L1596

It is possible this mistake is from an older version of the protocol, but using the MS reference, the current mapping in Windows has been the case since the earliest recorded spec from 8/8/2013.

If this issue is accepted I am happy to make a small PR to adjust this value.

CPython versions tested on:

3.11, 3.12, 3.13, CPython main branch

Operating systems tested on:

Windows

I think it's ok, and I have modified it

@rruuaanng - could you please elaborate further. What is ok? What have you modified?

[rruuaanng]

And you should bring the OS-windows label

[seanbudd]

@rruuaanng - I can't label issues, that's only for people with triage/write permissions

I changed kh_KH to km_KH

[seanbudd]

@rruuaanng - you manually changed it locally by patching it? That's not a solution for cpython. We should adhere to the standards set by Microsoft. this is an issue to fix it with cpython, not in your own project

I checked out the link you gave me at https://ss64.com/locale.html and fixed the issues you mentioned. Everything should be good to go now

@rruuaanng - how did you fix it? how did you test it?

@rruuaanng If this issue is valid (should be confirmed from locale experts, cc @malemburg), we need to send a PR with a fix, applying changes locally affects only your local git repository.

I checked the results of the windows_locale.get(int(code, 0)) statement to see if it gets the corrected value now.

windows_locale dictionary isn't used anywhere else, so I think fixing the source of the error should be enough.
