Re: [idn] opting out of SC/TC equivalence

["ben" <ben@cc-www.com>]

Although the current ccTLDs and gTLDs will work for IDNs, they cannot
totally satisfy the needs of the users of CDNs.  Another type of TLD
must be created and I will tentatively call it lsTLDs (Language Script
TLDs).  lsTLDs are in native language script... not English- thus
bringing out the issue of <IDN>.<IDN> that ICANN has already expressed
their interest in.

This is not just an issue for ICANN.  I do still need to write a draft
and submit it to the IDN WG because lsTLDs are not a simple straight
forward concept as ccTLDs and gTLDs.  2 techniques / mechanism must be
documented:

1.  A relationship exist between the <.traditional> and <.simplified>
lsTLDs
2.  During Nameprep, an error checking is done to disallow improper
characters for a lsTLD.

Thanks

         In  HongKong, people use BIG5 code that is major in
traditional
chinese characters,
After 1997,  Hong-Kong Goverment announce an extension set including
fonts
of TC/SC.
MicroSoft provided them with GBK code but display the message in TC
font.
GBK is the extension of GB, and  China use them in MicroSoft IE now.
GBK
include the font of some traditional chinese character.  The TC/SC
translation  majorly focus on BIG5 <-> UNICODE <-> GBK , especially
for BIG5
<--> GB/GBK.
         If TC/SC  one to one  font/script mapping is fiexed, it shoud
be
processed in normalization/unification phase .  But  one to many
font/script
mapping can not be easily solved by this way,  if the mixing type
<SC><TC><SC><TC>  are all one one mapping in each character then they
will
be reduced to one canonical  representation.  If the mixing type
including
one to many characters  one string are assigned by the registrant in
registration time.
         That draft is just to solve your 2  problems.  Hope these can
help
understanding.
