I was curious to find how fast or slow Encode is against popular
Japanese transcoder modules. So I benchmarked and relieved that
Encode's performance was good!
I benchmarked it against Jcode.pm (mine, too) and jcode.pl (the first
and still popular transcoder available since Perl4 by Utashiro-san) and
here is the result. Except for 7bit-jis (ISO-2022) <-> euc-jp Encode
performed the best. And even for those losing against Jcode.pm,
performance loss is not that big. Note Unicode conversion tests are
missing from jcode.pl because they are unimplemented thereby.
The Japanese has one more good reason to switch to Perl 5.8.
