The Linux kernel code has been rewritten to use Unicode to map
characters to fonts.  By downloading a single Unicode-to-font table,
both the eight-bit character sets and UTF-8 mode are changed to use
the font as indicated.

This changes the semantics of the eight-bit character tables subtly.
The four character tables are now:

Map symbol	Map name			Escape code (G0)

LAT1_MAP	Latin-1 (ISO 8859-1)		ESC ( B
GRAF_MAP	DEC VT100 pseudographics	ESC ( 0
IBMPC_MAP	IBM code page 437		ESC ( U
USER_MAP	User defined			ESC ( K

In particular, ESC ( U is no longer "straight to font", since the font
might be completely different than the IBM character set.  This
permits for example the use of block graphics even with a Latin-1 font
loaded.

In accordance with the Unicode standard/ISO 10646 the range U+F000 to
U+F8FF has been reserved for OS-wide allocation (the Unicode Standard
refers to this as a "Corporate Zone", since this is inaccurate for
Linux we call it the "Linux Zone").  U+F000 was picked as the starting
point since it lets the direct-mapping area start on a large power of
two (in case 1024- or 2048-character fonts ever become necessary).
This leaves U+E000 to U+EFFF as End User Zone.

The Unicodes in the range U+F000 to U+F1FF have been hard-coded to map
directly to the loaded font, bypassing the translation table.  The
user-defined map now defaults to U+F000 to U+F1FF, emulating the
previous behaviour.  This range may expand in the future should it be
warranted.

Actual characters assigned in the Linux Zone
--------------------------------------------

In addition, the following characters not present in Unicode 1.1.4 (at
least, I have not found them!) have been defined; these are used by
the DEC VT graphics map:

U+F800 DEC VT GRAPHICS HORIZONTAL LINE SCAN 1
U+F801 DEC VT GRAPHICS HORIZONTAL LINE SCAN 3
U+F803 DEC VT GRAPHICS HORIZONTAL LINE SCAN 7
U+F804 DEC VT GRAPHICS HORIZONTAL LINE SCAN 9

The DEC VT220 uses a 6x10 character matrix, and these characters form
a smooth progression in the DEC VT graphics character set.  I have
omitted the scan 5 line, since it is also used as a block-graphics
character, and hence has been coded as U+2500 FORMS LIGHT HORIZONTAL.
However, I left U+F802 blank should the need arise.  

Klingon language support
------------------------

Unfortunately, Unicode/ISO 10646 does not allocate code points for the
language Klingon, probably fearing the potential code point explosion
if many fictional languages were submitted for inclusion.  There are
also political reasons (the Japanese, for example, are not too happy
about the whole 16-bit concept to begin with.)  However, with Linux
being a hacker-driven OS it seems this is a brilliant linguistic hack
worth supporting.  Hence I have chosen to add it to the list in the
Linux Zone.

Several glyph forms for the Klingon alphabet have been proposed.
However, since the set of symbols appear to be consistent throughout,
with only the actual shapes being different, in keeping with standard
Unicode practice these differences are considered font variants.

Klingon has an alphabet of 26 characters, a positional numeric writing
system with 10 digits, and is written left-to-right, top-to-bottom.
Punctuation appears to be only used in Latin transliteration; it
appears customary to write each sentence on its own line, and
centered.  Space has been reserved for punctuation should it prove
necessary.

This encoding has been endorsed by the Klingon Language Institute.

Since the characters in the beginning of the Linux CZ have been more
of the dingbats/symbols/forms type and this is a language, I have
located it at the end, on a 16-cell boundary in keeping with standard
Unicode practice.

Other Fictional and Artificial Scripts
--------------------------------------

Since the assignment of the Klingon Linux Unicode block, a registry of
fictional and artificial scripts has been established by John Cowan,
<cowan@ccil.org>.  The ConScript Unicode Registry is accessible at
http://locke.ccil.org/~cowan/csur/; the ranges used fall at the bottom
of the End User Zone and can hence not be normatively assigned, but it
is recommended that people who wish to encode fictional scripts use
these codes, in the interest of interoperability.  For Klingon, CSUR
has adopted the Linux encoding.
