Well, mostly you don't need to do this. In fact, more often, when doing
typical web sites, reporting, and data processing, I need to get the
number of character positions a string will take up in a fixed-width
font; I'd be interested in seeing how well Python does with that.

However, to answer your question:

    class String
	def utf8_char_count
	    split('').select { |c| c[0] < 128 }.length
	end
    end

Now, for the rest of your program, you can just say String.utf8_char_count.
