Plans for 2.1: Unicode Support

• See #120
• See #344
• See #350
• See #355
• See #437
• See #484
• See #565

Notes I had lying around:

• File encoding (what do we do now? what if someone tries an ack UCS-2-file?)
• ARGV encoding
• Document new regex-fu that came with 5.14?
• Filename/pattern normalization
• Output stream encoding
• Collation level is something I mentioned
• I18N::Langinfo
• Coloration + unicode chars
