Noted.

There are some UTF-8/UTF-16 interoperability aspects that are addressed
by CESU-8. These concerns are real, and affect multi-component architectures
that must interchange data across component boundaries. Therefore a standard
specification serves a useful purpose.

Phillippe doesn't worry me ;-)

You realize that the choice of material for a UTN rests with the authors.
Occasionally that will mean that material that could be a formal
specification is placed into a UTN by an author uninterested in getting UTC
endorsement, or one that lacks the time to pursue such.
In the case of BOCU-1 it's the latter, as the UTC has welcomed the idea of
putting this on a standards track.
So, your remarks should be directed at the authors of the UTN, and/or the
owners of the relevant technology.
