This PR is a partial fix for #80667, resolving inconsistent treatment of case in Unicode literal escape sequences. This changeset should be compatible with the changes in #101585 as well as named ranges that may be introduced in the future.

I did not realize when I wrote this patch last night that PyOS_strnicmp() existed, I've rewritten the patch to use it instead, avoiding the issues that were caused by the string copying approach. Ready for review.

Sorry, @SnoopJ and @serhiy-storchaka, I could not cleanly backport this to 3.13 due to a conflict.
Please backport using cherry_picker on command line.
