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.
