Ah, you have three bytes, 232, 192, 153 in utf8 representation and want to
convert those into a unicode codepoint. Here I have a binary with a bit of
other utf8 characters in it (since ASCII and utf8 overlaps):

9> B = <<232, 191, 153, $h, $e, $l, $l, $o>>.
<<232,191,153,104,101,108,108,111>>
10> [CP || <<CP/utf8>> <= B].
[36825,104,101,108,108,111]
