Re: [idn] Problems in normalisation and matching

Copy-and-paste *operation*   is not only a user interface but also a trigger to
a critical system service  for interprocess communications between independant applications  
like unix & NT-pipe or socket ,and it transfers some data from one application to the other 
with  conversions or transcodings. 

Some IETF protocols (TCP/IP) are often very strict at forcing on-the-wire communication octets streams to be 
little-endian and big-endian. Cut-and-paste is a popular communication tool and have much more
stricter rules and conventions for various data formats (images, sounds , URLs and texts ). 
IDN specifications can recommends special treatements of IDN or IDN-like strings in text copy&paste operation.

Identifier security and integrity issue around copy-and-paste operation still 
is of the concern of this WG.
