COMMENT:
----------------------------------------------------------------------

I like the clear explanation of some of the design choices in here (e.g., the
rationale for using NFKC).

There are two places that I think a slight bit of additional text might be
useful:

1. When talking about processing "each string" in section 2.4, it's probably
worth noting that implementations should be careful not to assume that any
information received from a wire protocol has necessarily had any of the rules
in this document applied to it (as this might allow intentionally noncompliant
clients to slip certain kinds of shenanigans past their checks); and

2. Where the final paragraph of section 4 indicates that the operations in this
document are not necessarily idempotent, it is probably worth being more
explicit that they should be applied repeatedly until the output string is
stable; or, if the string does not stabilize after a reasonable number of
iterations (is this possible?), that it should be rejected as invalid.
