I'm not asking for planning (or any other action) for 0.001% corner
cases.  I am suggesting that it would be helpful to move away from
what I read as the apparent "all displayable characters in Unicode
are equal" language of the current text and explicitly allow (and
request) the RPC to establish a list of scripts (and, where
applicable, languages) that they are ready to handle expeditiously.
If my three-tier suggestion is too complicated, it can easily be
turned into that one versus "everything else", with the RPC growing
that list incrementally as experiences with a broader range of
scripts, characters, and writing systems accumulates.

That would also avoid another aspect of your suggestion: it would,
almost inevitably, result in a document making it all the way through
the system, making into it to the RPC's hands when authors/editors
(and sometimes the process in the streams) are already a bit worn
out, only to have the RPC say what would translate into "whoops, that
does not work, start rewriting".  In addition to the obvious
inefficiency, it would tend to reduce transparency to those in the
community who might want to check on the replacement version.  

It just seems to me that having the RPC identify what they can handle
well and easily (in some way I'm happy to have them work out) so that
document writers will know that other things may require some
additional time, expertise, and possible rewriting, or that
consulting the RPC while the writing work is still in progress would
be a good idea, would benefit everyone.  And it would probably save
the RPC work rather than putting more burden on them.

Sadly, no surprise.
