About String#upcase, our current answer is simple: use ICU. https://github.com/jarib/ffi-icu ---------------------------------------- Feature #2350: Unicode specific functionality on String in 1.9 http://redmine.ruby-lang.org/issues/2350 Author: Manfred Stienstra Status: Rejected Priority: Normal Assignee: Category: Target version: I was wondering is there are any plans to include Unicode aware methods for Unicode encodings on String? For example, upcase and downcase only handle ASCII characters at the moment. cafe = "Caf��" cafe.encoding # => # "Caf��".upcase # => CAF�� -- http://redmine.ruby-lang.org
