- # "a".ord # => 97

- # Ruby 1.9 on UTF8 strings:
- #
- # "a".mb_chars.ord # => 97
- # "à".mb_chars.ord # => 224, in UTF8
- #
- # Note that the 224 is different in both examples. In ISO-8859-1 "à" is
- # represented as a single byte, 224. In UTF8 it is represented with two
- # bytes, namely 195 and 160, but its Unicode codepoint is 224. If we
- # call +ord+ on the UTF8 string "à" the return value will be 195. That is
- # not an error, because UTF8 is unsupported, the call itself would be
- # bogus.
