Perl is specifically documented to not do this for backward compatibility
reasons. In Perl, which is the one I know best, you are required to
decode input and encode output if you want to have UTF-8 handling.
windlord:~> env LC_CTYPE=en_US.UTF-8 perl -e 'print "\x{00a3}\n"'
<glyph for mangled Unicode character>
windlord:~> env LC_CTYPE=en_US.UTF-8 perl -MEncode -e 'print encode("utf-8",
"\x{00a3}\n")'
<proper Unicode pound sign>
See perlunicode(1). There are a variety of reasons for this that turn out
to be fairly good ones if you don't want to badly break a bunch of
existing Perl scripts that were dealing with, for example, binary data.
