I am using a web framework(Chicagoboss). I posted the data into Erlang in Chinese in utf8 encoded string from a web form. It is read by Erlang as [232,191,153]. This is just one single Chinese character. But erlang read it as [232,191,153]. So I want to consume via ajax later on on the client side.

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>>

[36825,104,101,108,108,111]
