    It is not a difference between ANSI and unicode but between unicode code
    points and the UTF-8 encoding scheme.

    The unicode code point for é is indeed the same, as can be seen here:

    é 233 233 0xE9 U+00E9 é
    Latin small letter e with acute Latin-1 Supplement

    For the difference between code points and UTF-8 see sections 2.5 and 2.6 of
    chapter 2 of the standard.
