How to capitalize nonascii characters?

Ruby
1

#capitaize not working here as documented -

Returns a copy of str with the first character converted to uppercase
and the remainder to lowercase. Note: case conversion is effective
only in ASCII region.

(arup~>~)$ pry --simple-prompt

s = “école”
=> “école”

s.capitalize
=> “école”

How to do this here?

Dear Arup,

I don’t know if this is the current answer.
I was just curious and googled a little and found this.

gem install unicode

#!/usr/bin/env ruby
#coding: utf-8

require ‘unicode’

puts Unicode::capitalize(“cole”)

Unicode does it. I’m having a problem getting it deployed at the
moment because the deployment server is in rather a strange state, but
the gem itself works a treat. My problem space was different, as I
needed to ensure email addresses were unique in spite of having
different cases, but unicode solved the problem.

Hi,

Yes, use unicode gem for now. String operations on non ASCII
characters are one of the topics for upcoming Ruby 2.2.
