You are confused between unicode characters and unicode codepoints.
Every unicode codepoint has exactly one UTF-8 representation.
Unicode characters may use one ore more unicode codepoints.
Some characters have also representation with one codepoint, but not all.
For example
LATIN CAPITAL LETTER A WITH ACUTE
have presentation 0041 0301
That is two unicode codepoints. That character
have also other (compatibility) representation
that is 00C1
But consider (somewhat imaginary) character
LATIN CAPITAL LETTER A WITH GRAVE AND CIRCUMFLEX
that have presentation 0041 0300 0302
but it have also presentation 0041 0302 0300
Both presentations are equal short.
