Using ISO-10646-UCS-2 will cause a problem when we use our own
iconv functions in the future, or port iconv other than GNU
libiconv.
Each vendors treat "UCS-2" as follows, and endian issue is
vendor specific:
- Solaris 8 iconv
Little Endian with BOM
- HP-UX iconv
Big Endian
- NetBSD/i386 1.6 iconv
Little Endian
- GNU libiconv
Big Endian
- glibc(RedHat AS 2.1 x86) iconv
Little Endian
- IANA
Name: ISO-10646-UCS-2
MIBenum: 1000
Source: the 2-octet Basic Multilingual Plane, aka Unicode
this needs to specify network byte order: the standard
does not specify (it is a 16-bit integer space)
Alias: csUnicode
- MSDN
Little Endian

Now using UTF-16BE is harmless, because
- same as UCS-2 with 2 byte range (U+0000 - U+FFFF)
- kernel code of each file systems(cd9660, msdosfs, ntfs) believes
Unicode is a 2 byte character at this time.
- UDF has only 2 byte range of Unicode filenames.
- It's defined at RFC2781.
So I believe it's time to change before starting new RELENG_6. :)

This is the top level of the FreeBSD source directory. This file was last revised on: $FreeBSD$ For copyright information, please see the file COPYRIGHT in this directory (additional copyright information also exists for some sources in this tree - please see the specific source directories for more information). The Makefile in this directory supports a number of targets for building components (or all) of the FreeBSD source tree, the most commonly used one being ``world'', which rebuilds and installs everything in the FreeBSD system from the source tree except the kernel, the kernel-modules and the contents of /etc. The ``buildkernel'' and ``installkernel'' targets build and install the kernel and the modules (see below). Please see the top of the Makefile in this directory for more information on the standard build targets and compile-time flags. Building a kernel is a somewhat more involved process, documentation for which can be found at: http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/kernelconfig.html And in the config(8) man page. Note: If you want to build and install the kernel with the ``buildkernel'' and ``installkernel'' targets, you might need to build world before. More information is available in the handbook. The sample kernel configuration files reside in the sys/<arch>/conf sub-directory (assuming that you've installed the kernel sources), the file named GENERIC being the one used to build your initial installation kernel. The file NOTES contains entries and documentation for all possible devices, not just those commonly used. It is the successor of the ancient LINT file, but in contrast to LINT, it is not buildable as a kernel but a pure reference and documentation file.
