Question

In another question it was asked how to replace Umlaute. The accepted question was the following code:

# encoding: utf-8
foo = "ich bin doch nicht blöd, mann!".gsub(/[äöü]/) do |match|
    case match
        when "ä" 'ae'
        when "ö" 'oe'
        when "ü" 'ue'
    end
end
puts foo

However, when I try to run this, the output is:

$ ruby /tmp/test.rb 
ich bin doch nicht bld, mann!

So the Umlaute obviously don’t get replaced. Is there something I am missing? I’m using Ruby 1.9.3p362 (2012-12-25 revision 38607) [x86_64-linux]

Answer 1

"ich bin doch nicht blöd, mann!".gsub("ä","ae").gsub("ö","oe").gsub("ü","ue")

Should do the trick
