Gentle e-mail recipients,
I have a few questions about the wiley T.61 String ASN.1 type.
(Apologies to those who are on both e-mail lists.)
1. I have a copy of the 1984 X.208 which (in table 6, page 44) lists
the T61 String registration numbers as 87, 102, 103, 106, 107 SPACE
and DELETE. Does anyone have a 1988 or 1992 version of X.208 ? Are
there changes to this list ?
2. Does anyone have a mapping from the ISO IR numbers (87, 102,...) to
the pertinent ISO standards (ISO 646 ?, ISO 6937 ?, ISO 8859 ?) ?? ???
3. Is anyone working on (...is there a need for...) implementor's
agreements for the use of T.61 String in PEM certificates and MIME
messages ? This is an area of great ambiguity IMHO. E.g. Do ESC
sequences that change character sets apply to whole distinguished
names or just to the AVA in which they appear ? Can I change a
character set in the middle of an AVA (mail message, whatever) ?
4. Is there anyone that has a good grasp of all of the relevant issues
surrounding T.61 ? Should I wait for ISO 10646 and Unicode ? (somewhat
Any clues are appreciated.
