str = 'Hello, world!?'
str.scan(/[a-df-hj-np-tv-z]/i).size

=> 7

str.gsub(/[^a-df-hj-np-tv-z]/i,'').size

=> 7

Whoops. That should be ... count("a-zA-Z", "^aeiou"). You can read that
statement as: count() all the characters which are in the ranges
"a-zA-Z" AND which are NOT "aeiou".

(a is a vowel...)

I'd suggest this:

> s = 'Helloooo my wonderfuuuuul peeeopulllaaaa. IIII am come!!'
=> "Helloooo my wonderfuuuuul peeeopulllaaaa. IIII am come!!"
> s.scan(/[^aeiou]+/i).join('')
=> "Hll my wndrfl pplll. m cm!!"
> s.scan(/[^aeiou]+/i).join('').size
=> 28

... and that counts non-alphas.

s.scan(/[[:alpha:]]+/i).join.scan(/[^aeiou]+/i).join.size
