1. What is difference between those two calls?
utf8::encode($str);
and
$str = Encode::encode('utf8', $str);
2. What is difference between those?
utf8::decode($str);
$str = Encode::decode_utf8($str);
They do the same thing with different interfaces. utf8::encode/decode
modify a string in-place and return a boolean to signal success or not.
Encode.pm returns a copy and can be configured to do a range of things
with invalid input, from converting invalid bytes to replacement marks
to throwing an exception.
3. Where is implementation of utf8::encode/decode functions? It is not
in utf8.pm, nor in utf8_heavy.pl and also not in unicore/Heavy.pl. And
what those functions doing?
They are part of the perl interpreter and defined in universal.c as thin
wrappers around code ultimately from sv.c.
