OVERVIEW

This project proposes the common Unicode encoding conversion functions at
the kernel. Specifically, this project will supply conversions among UTF-8,
UTF-16, and UTF-32 with options to specify on the desired byte orderings for
UTF-16 and UTF-32 as described in the [1].

The immediate requesters and users of the functions are pcfs, ldterm, and
udfs.

The Unicode and ISO/IEC 10646 standards defines and endorses UTF-8, UTF-16,
and UTF-32 as the standard Unicode / ISO/IEC 10646 encoding forms. (There
are also UTF-16BE, UTF-16LE, UTF-32BE, and UTF-32LE encoding forms also
endorsed where "BE" stands for Big Endian and "LE" stands for Little Endian.
UCS-2, UCS-4, UTF-7 and such are all deprecated and strongly discouraged by
the Unicode consortium and also by the ISO/IEC JTC1/SC2/WG2.)
