I want to enable Encode::HanExtra on Windows XP environment. I can't find the name HanExtra or Encode-HanExtra in PPM GUI. Is there any alias name for it？
Encode-HanExtra does exist according to this page but there is no Windows build. Some options:
Encode::CNMap can convert between many different Chinese encodings (gb2312, big5, utf8, gbk). ActivePerl name is Encode-CNMap.
There is an ActivePerl version of Encode::CN::Utility which can convert characters between Hanzi, GBK and Unicode/UTF-8. ActivePerl name is Encode-CN-Utility.
You could install Strawberry Perl instead of ActivePerl. This is a community distribution of Perl for Windows that uses CPAN, so any module on CPAN can be installed (except platform-dependent modules). After installing run cpan Encode::HanExtra.
You could build your own PPM version of Encode::HanExtra (not recommended)
