Hi, gurus

I know that ruby handles unicode, and I suppose it handles ascii as a
subset of unicode, m need is to have a Range like
"\000\000\000".."\255\255\255"   [1]

or, if you like, this more:
"aaa".."zzz"+$all_the_strange_chars

I tried to use the previous [1] way to obtain this, but it seems to
fail, giving me an array with 58 (!) elements.
How could I iterate over strings like this ?
