[erlang-questions] Jinterface OtpErlangBinary utf-8 double encoding

[Carl-Johan Kjellander]

(moose@REDACTED)58> <<_:8, A1/utf8, A2/utf8>> = <<"Föö">>.
** exception error: no match of right hand side value <<"Föö">>

So what is the correct way of seeing it in the shell? Should I see it as
the correct character or the utf-8 encoded ones?

/cjk
