UTF-8 question

The problem is that Ruby Strings are still logically treated as
collections of bytes rather than collections of characters. So
String#tr only works for characters whose representation takes up a
single byte - which, in the case of UTF-8, means only the 7-bit
ASCII characters.

Yeah, that’s what I guessed.

To avoid the unightly gsub chaining, you can write your own tr-like
method that takes an array of regexes and a corresponding array
of substitutions:

It should probably be:

class String
def trsub!(res, subs)
last = subs[-1] || ‘’
res.each_with_index do
>re, i|
self.gsub!(re, subs[i] || ‘’)
self.gsub!(re, subs[i] || last)
end
end
end

s.trsub!(%w<ñ á é í ó ú ü ¡ ¿>, %w)

Yeah, i’ve thought of this as well. However, it feels like it will be
rather slow. OK, given the input strings are rather short ;-), so I
guess it will do. Thanks,
