A question for you DEC "i18n" gurus.

On a vt100/vt102 (?), ESC} (escape close curly brace) and ESC| (escape
vertical bar) are the escape sequences used to designate JIS X0201
Kana (single byte Kana) strings.

Assuming that the ASCII set has been designated into G0 and G3, JIS
X0208 has been designated into G1, and JIS X0201 into G2:

(1) Is this an acceptable arrangement of codeset grouping?

(2) If so, then once an ESC| does a locking shift of G3 into GR, how
    does one determine when to do a locking shift of G1 into GR?

(3) If one of the ISO 8859 codesets is being used (instead of ASCII)
    in conjunction with a JIS X0201/X0208 environment, are there
    special codeset announcement mechanisms used to remove potential
    ambiguities between the ISO 8859 set and JIS X0208 set?

Or in lieu of answers, can someone point out a DEC contact for
internationalization questions?

Thanks!
