I (purposefully) left the O(1) stuff out of it.  I left out the \U+
syntaxes.  I left out the 256-characters recommendation.  I left out
the ASCII recommendation.  I even left out the "string indexes are
codepoint indexes if the string is made up of codepoints".

I left out everything that was "advice" rather than "requirement" and
left out everything that could be handled in a separate SRFI.  By
startling coincidence (not!), that meant that I left out very nearly
everything that raised any sort of controversy at all in preceding

In my opinion, at least at the moment, what's left is necessary and
sufficient for R6RS to adopt to be Unicode-friendly and
extended-character-set-friendly generally.  Everything else can be
additional SRFIs (\U+ syntax, string-index meanings for Unicode
strings) or folklore ("hey, O(1) string-ops are good").
