Stephen,
Only the 7 bit ASCII characters are the same. UTF-8 encodes characters so
that you can tell how many bytes the character will take from the value of
the first byte of the character.
0x00 - 0x7F = 1 byte
0xC0 - 0xDF = 2 bytes
0xE0 - 0xEF = 3 bytes
0xF0 - 0xF7 = 4 bytes
0x80 - 0xBF is used for continuation bytes. These are the 2nd, 3rd or 4
bytes of a character. This make it easy to find the beginning of a
character.
0xF8 - 0xFF are not used by Unicode.
