Re: plain ASCII version of TSCII charset registration request
Dear Martin:
Updated version of TSCII <--> Unicode mapping table is now available
at the Unicode.org website under URL
http://www.unicode.org/notes/tn15/tn15-2.html
This URL is indicated within the general URL given for the tech.note
#15.
This takes care of the point raised by Ken Whistler.
Can you please advice us on any other changes that you would like to
see in the plain ASCII version of TSCII charset registration request
that I posted earlier for it to meet the approval of IETF reviewers?
