Subject: [ruby-core:83576] [Ruby trunk Feature#14055] String#casecmp should	use Unicode folding

Issue #14055 has been updated by rbjl (Jan Lelis).


Thanks for the pointer!

----------------------------------------
Feature #14055: String#casecmp should use Unicode folding
https://bugs.ruby-lang.org/issues/14055#change-67604

* Author: rbjl (Jan Lelis)
* Status: Rejected
* Priority: Normal
* Assignee: 
* Target version: 
----------------------------------------
The following string and symbol methods are currently only ASCII aware:

- String#casecmp
- String#casecmp!
- Symbol#casecmp
- Symbol#casecmp!

For example:

    "a".casecmp("A") #=> 0
    "��".casecmp("��") #=> 1

Now that Ruby has implemented case-folding (which is meant for comparing strings, see http://unicode.org/faq/casemap_charprop.html#2), it should be used when doing a casecmp on Unicode strings:

    "��".downcase(:fold) == "��" #=> true
