Overview

Package idna implements IDNA2008 using the compatibility processing defined by UTS (Unicode Technical Standard) #46, which defines a standard to deal with the transition from IDNA2003.

IDNA2008 (Internationalized Domain Names for Applications), is defined in RFC 5890, RFC 5891, RFC 5892, RFC 5893 and RFC 5894. UTS #46 is defined in http://www.unicode.org/reports/tr46. See http://unicode.org/cldr/utility/idna.jsp for a visualization of the differences between these two standards.
