How do I use String methods on UTF-8 characters?

Question

How do I use String methods on UTF-8 characters?

For example, I have a string with Cyrillic characters, so when I use string.upcase it doesn\'t work.

Answer 1

The rails active_support gem has string extensions that can handle this.

For example:

# $ sudo gem install activesupport
require 'active_support/core_ext/string'
'Laurent, où sont les tests ?'.mb_chars.upcase.to_s
# outputs => "LAURENT, OÙ SONT LES TESTS ?"
