Always getting error unknown from error messages

[VwertIX]

So I deliberately deleted a letter from the value string to check out the error it would send and it shows

but if i put the error code into the FormatMessageW function it gives the proper system error message for error code 2

Which is "The system cannot find the file specified."

It could be that theres something wrong with my computer or something.

Ok so apparently error messages are messed up if your locale is set to en-gb.
If I change the language value for FormatMessageW to 2057 which is the one for en-gb it fails whereas if its set to 1033 which is en-US it works.

Looks like its __std_system_error_allocate_message in syserror_import_lib.cpp causing it.
Apparently its been fixed but the fixed version of it hasn't been released yet.
microsoft/STL#3254
microsoft/STL#5104

OK, so it seems a regression introduced in VS 2022, right?
I can leave my code unchanged, and wait for proper fixes in Microsoft's code.
What do you think?

Since this looks like a bug introduced at some point in VS 2022, and that was fixed (even if the fixed version has not been released yet), and I got no further feedback from you, I'm closing this issue.
