Change decimal symbol for jp-JP and ch-ZH

[U52284]

Hello,

After updating our apps and modules to .NET 10, I'm getting failed tests. It seems that the decimal sign is not "." (dot) anymore fore ch-ZH and jp-JP (at least) but "," (comma).

Is this something that changed now or how does that difference come? We have 5 cultures in teh test, these two fail. Don't know if others also are affected. I have seen no changes mentioned in the dotnet update info about CultureInfo changing.

Thanks in advance
Patrick

You should not be testing the result of formatting with "real" cultures. The rules can change at any time (typically through a Unicode ICU or an OS update). #117602 (comment) #109409 (comment)

Thats a good point. I then might change on how the test works to make it consider that. That would also explain the change.

I've never heard of the decimal separator being a comma in a Japanese (ja-JP) environment. What's common in Japan is when it mistakenly defaults to InvariantCulture, but even then the decimal separator remains a period. Isn't this simply an issue where the culture isn't set correctly, causing it to default to your system's culture? Does the issue still occur if you set the locale to ja-JP instead of jp-JP?

Regarding Chinese, shouldn't it be zh-CN instead of cn-ZH?

I think that was maybe done wrong by another dev. but wouldnt the test fail if i try to creeate a CultureInfo object with a not existing culture?

anymore fore ch-ZH and jp-JP

It's zh-CN and ja-JP instead of ch-ZH and jp-JP.

Ah yes sorry. I typed it a few times and didnt revise again. Yes those two. But i have it correct in my test, just mentioned it wrong here.. Will correct it in the original post.

The point is that these two seem to have changed.
