PolishChars

Gem extends the Ruby String class methods, such as #downcase and #upcase by handling Polish diacritics. It also adds #no_pl method. It's much faster then gem named polskie_stringi.

Add this line to your application's Gemfile:

gem 'polish_chars'

And then execute:

$ bundle

Or install it yourself as:

$ gem install polish_chars

Example:

require "polish_chars"

text = "Zażółć Gęślą Jaźń"
text.downcase   # => "zażółć gęślą jaźń"
text.upcase     # => "ZAŻÓŁĆ GĘŚLĄ JAŹŃ"
