running away but a quick idea: you could use Integer#chr to get a char
(well, a one-byte-string) from an integer.
And, since you're dwelling with bytes anyway, you could just do a test
like
 if c =~ ?a..?z
(?a being the literal to get the integer value of a character)

So something like:
 gets.downcase.each_byte {|b| h[c.chr] += 1 if c =~ ?a..?z}
