UTF-8 BOM is prepended.

The function is available from the stub library, in
order to bring the responsibility for correct linking
to the embedding application, in stead of Tcl. In
case of tclsh.exe, this makes no difference.

In additon, starting with Tcl 9.0, the default
panic proc is changed to direct the output to the
UI in stead of stderr. Since the new _Tcl\_ConsolePanic_
is meant for stderr-related output, this means
that Tk (or other applications embedding Tcl) don't
have to do anything special to have a UI-based
panic proc.

This document proposes:

 * Add a new objType "UTF-32", which is able to store a string in 32-bits
   per character.

 * Adapt the regexp engine to start using the "UTF-32" objType: Any string
   handled by regexp will first be converted to "UTF-32".

 * Modify all API using Tcl_UniChar: If the string contains surrogate pairs,
   the "UTF-32" objType will used.

 * Modify all functions using or producing an index: "string length <Unicode>"
   should return 1 for all Unicode characters, even the ones >= **U\+010000**

TODO: everything else that comes up

# Compatibility

TODO


# Reference Implementation

A reference implementation is not started yet.
