G'day vsespb,

The current version of Perl (5.18.1) supports Unicode 6.2. This support started with the previous version (5.18.0) - see perl5180delta.

I'm not aware of a table (or similar) specifically mapping Perl versions to Unicode versions; however, the deltas listed here should document changes in Unicode support.

For testing edges cases, etc. across multiple Perl version, these may prove useful:

• Test::More - for writing the tests.
• App::perlbrew - for easily installing different Perl versions and switching between them.
• Online Perldoc allows you to select the documentation for Perl versions 5.8.8 to 5.18.0 [at the time of writing].

Other Perl Unicode documentation that may be helpful:

• perluniintro - Perl Unicode introduction
• perlunitut - Perl Unicode tutorial
• perlunifaq - Perl Unicode FAQ
• perlunicode - Perl Unicode support
• perluniprops - Index of Unicode properties in Perl
