Unicode defines a notion of how can specify the sorting name inside the culture name. It does that using the term
u-co
. For example,zh-TW-u-co-zhuyin
meant to be thezh-TW
culture with sort behavior ofzhuyin
. Such a name will be resolved tozh-TW@collation=zhuyin
in ICU.Names with
u-co
used to work fine in .NET 5.0 when running on Windows but was failing on other platforms like Linux. So, this seems a regression but was not perfect anyway in .NET 5.0 either. The change here is to allow such culture names to work in all platforms and behave as expected too, especially when sort names are specified.
