desperate looking for a way of a more relaxed way of searching a string inside another, we need not to take into the account not only the case

s = "Abc" if s =~ /abc/i then …

but also if you have forgotten an accent, etc:

s = "áBc" if s =~ /abc/i then …also should match!

Changing the encoding to the simplest one: ASCII, does not work since iconv, nor ruby force_encoding() work and gives you errors in case you try to convert "á" to "a"

This might be one option for you:

$ irb -KU -r iconv

...

s = "áBc"

=> "áBc"

...

Iconv.conv("ASCII//TRANSLIT//IGNORE", "UTF-8",

s).downcase.delete("^a-z") =~ /abc/ => 0

I hope that helps.
