This forbids, among others, ISO 10646 UCS-2 and EBCDIC as text/plain
character sets.

I assumed that what is called UCS-2 is the same thing as what
in "The Unicode Standard, Version 1.1, Appendix F", is called
FSS-UTF, i.e. Filesystem Safe UCS Transformation Format.

No, UCS-2 is the 2-byte form of ISO/IEC 10646
    UCS-4 is the 4-byte form of ISO/IEC 10646

    UTF-1 is the first 16-to-(n*8) bits method for UCS; is in the
          standard but is proposed to be removed
    UTF-8 corresponds to FSS-UTF (exactly?) ((32 or 16)-to-(n*8) bits)
    UTF-16 is the proposed "enlargement" of BMP (~20-to-(2*16) bits)

I'm not updated on the formal state of the latter two

And then there is the Internet-experimental UTF-7
(MIME charset UNICODE-1-1-UTF-7, RFC 1642), 16-to-(n*7) bits.
