Libidn is a modern library to perform internationalized string
processing based on the Stringprep, Punycode, Internationalizing
Domain Names in Applications (IDNA) specifications.  Libidn contains
interfaces for C, Java, C# and Emacs Lisp.

* Version 0.6.11 (released 2007-03-13)

** Update of the C# Libidn port, by Alexander Gnauck.
The code has been refactored and the namespace has been modified to
comply with .NET naming conventions.  An IDNA bug was fixed.

** Update gnulib files.
We now use the "striconv" module instead of the "iconvme", which
causes a slight increase of code size (from 303kb to 319kb with
debugging symbols on i386).  The reason is the use of a new locale
independent strcasecmp, which may cause faster operation in some
locales where, e.g., "ASCII" and "ascii" are not treated as the same.

** API and ABI is backwards compatible with the previous version.

The library contains a generic Stringprep implementation that does
Unicode 3.2 NFKC normalization, mapping and prohibitation of
characters, and bidirectional character handling.  Profiles for
Nameprep, iSCSI, SASL and XMPP are included.  Punycode and ASCII
Compatible Encoding (ACE) via IDNA are supported.  A mechanism to
define Top-Level Domain (TLD) specific validation tables, and to
compare strings against those tables, is included.  Default tables for
some TLDs are also included.  Finally, the library can detect "problem
sequences" that may trigger bugs in various NFKC implementations.

Improving Libidn is costly, but you can help!  We are looking for
organizations that find Libidn useful and wish to contribute back.
You can contribute by reporting bugs, improve the software, or donate
money or equipment.

Commercial support contracts for Libidn are available, and they help
finance continued maintenance.  Simon Josefsson Datakonsult, a
Stockholm based privately held company, is currently funding Libidn
maintenance.  We are always looking for interesting development
projects.  See for more details.
