Is there a way to cause Encode to display warnings for upper ascii
outside of the Big5 range when converting from Big5 to Unicode? If not, could
the developers consider this for a future fix?
Use the optional 3rd argument to decode().
$utf8 = decode("Big5" => $big5); # ill-formed chars are mapped to U+FFFD
$utf8 = decode("Big5" => $big5, Encode::FB_WARN); # same but warnings issued
see "Handling Malformed Data" of "perldoc Encode" for how to use the 3rd argument.
