* Copyright (C) 2001, 2002, 2003, 2005, 2006, 2007, 2009 by Larry Wall,
* Nick Ing-Simmons, and others

*
* Macros to implement UTF-EBCDIC as perl's internal encoding
* Taken from version 7.1 of Unicode Techical Report #16:
* http://www.unicode.org/unicode/reports/tr16
*
* To summarize, the way it works is:
* To convert an EBCDIC character to UTF-EBCDIC:
* 1) convert to Unicode. The table in this file that does this is for
* EBCDIC bytes is PL_e2a (with inverse PLa2e). The 'a' stands for
* ASCIIish, meaning latin1.
* 2) convert that to a utf8-like string called I8 with variant characters
* occupying multiple bytes. This step is similar to the utf8-creating
* step from Unicode, but the details are different. There is a chart
* about the bit patterns in a comment later in this file. But
* essentially here are the differences:
* UTF8 I8
* invariant byte starts with 0 starts with 0 or 100
* continuation byte starts with 10 starts with 101
* start byte same in both: if the code point requires N bytes,
* then the leading N bits are 1, followed by a 0. (No
* trailing 0 for the very largest possible allocation
* in I8, far beyond the current Unicode standard's
* max, as shown in the comment later in this file.)
* 3) Use the table published in tr16 to convert each byte from step 2 into
* final UTF-EBCDIC. The table in this file is PL_utf2e, and its inverse
* is PL_e2utf. They are constructed so that all EBCDIC invariants remain
* invariant, but no others do. For example, the ordinal value of 'A' is
* 193 in EBCDIC, and also is 193 in UTF-EBCDIC. Step 1) converts it to
* 65, Step 2 leaves it at 65, and Step 3 converts it back to 193. As an
* example of how a variant character works, take LATIN SMALL LETTER Y
* WITH DIAERESIS, which is typicially 0xDF in EBCDIC. Step 1 converts it
* to the Unicode value, 0xFF. Step 2 converts that to two bytes =
* 11000111 10111111 = C7 BF, and Step 3 converts those to 0x8B 0x73. The
* table is constructed so that the first bytes of a variant will always
* have its upper bit set (at least in the encodings that Perl recognizes,
* and probably all).
*
* If you're starting from Unicode, skip step 1. For UTF-EBCDIC to straight
* EBCDIC, reverse the steps.
*
* The EBCDIC invariants have been chosen to be those characters whose Unicode
* equivalents have ordinal numbers less than 160, that is the same characters
* that are expressible in ASCII, plus the C1 controls. So there are 160
* invariants instead of the 128 in UTF-8. (My guess is that this is because
* the C1 control NEL (and maybe others) is important in IBM.)
*
* The purpose of Step 3 is to make the encoding be invariant for the chosen
* characters. This messes up the convenient patterns found in step 2, so
* generally, one has to undo step 3 into a temporary to use them. However,
* a "shadow", or parallel table, PL_utf8skip, has been constructed so that for
* each byte, it says how long the sequence is if that byte were to begin it
*
* There are actually 3 slightly different UTF-EBCDIC encodings in this file,
* one for each of the code pages recognized by Perl. That means that there
* are actually three different sets of tables, one for each code page. (If
* Perl is compiled on platforms using other EBCDIC code pages, it may not
* compile, or silently mistake it for one of the three.)
*
* EBCDIC characters above 0xFF are the same as Unicode in Perl's
* implementation of all 3 encodings, so for those Step 1 is trivial.
*
* (Note that the entries for invariant characters are necessarily the same in
* PL_e2a and PLe2f, and the same for their inverses.)
*
* UTF-EBCDIC strings are the same length or longer than UTF-8 representations
* of the same string. The maximum code point representable as 2 bytes in
* UTF-EBCDIC is 0x3FFF, instead of 0x7FFF in UTF-8.
