9 * Macros to implement UTF-EBCDIC as perl's internal encoding
10 * Taken from version 7.1 of Unicode Techical Report #16:
11 * http://www.unicode.org/unicode/reports/tr16
fe749c9a
KW		 12 *
13 * To summarize, the way it works is:
14 * To convert an EBCDIC character to UTF-EBCDIC:
d06134e5 15 * 1) convert to Unicode. The table in this file that does this for
fe749c9a
KW		 16 * EBCDIC bytes is PL_e2a (with inverse PLa2e). The 'a' stands for
17 * ASCIIish, meaning latin1.
d06134e5
KW		 18 * 2) convert that to a utf8-like string called I8 (I stands for
19 * intermediate) with variant characters occupying multiple bytes. This
20 * step is similar to the utf8-creating step from Unicode, but the details
21 * are different. This transformation is called UTF8-Mod. There is a
22 * chart about the bit patterns in a comment later in this file. But
fe749c9a
KW		 23 * essentially here are the differences:
24 * UTF8 I8
25 * invariant byte starts with 0 starts with 0 or 100
26 * continuation byte starts with 10 starts with 101
27 * start byte same in both: if the code point requires N bytes,
28 * then the leading N bits are 1, followed by a 0. (No
29 * trailing 0 for the very largest possible allocation
30 * in I8, far beyond the current Unicode standard's
31 * max, as shown in the comment later in this file.)
32 * 3) Use the table published in tr16 to convert each byte from step 2 into
d06134e5
KW		 33 * final UTF-EBCDIC. That table is reproduced in this file as PL_utf2e,
34 * and its inverse is PL_e2utf. They are constructed so that all EBCDIC
35 * invariants remain invariant, but no others do. For example, the
36 * ordinal value of 'A' is 193 in EBCDIC, and also is 193 in UTF-EBCDIC.
37 * Step 1) converts it to 65, Step 2 leaves it at 65, and Step 3 converts
38 * it back to 193. As an example of how a variant character works, take
39 * LATIN SMALL LETTER Y WITH DIAERESIS, which is typicially 0xDF in
40 * EBCDIC. Step 1 converts it to the Unicode value, 0xFF. Step 2
41 * converts that to two bytes = 11000111 10111111 = C7 BF, and Step 3
42 * converts those to 0x8B 0x73. The table is constructed so that the
43 * first byte of the final form of a variant will always have its upper
44 * bit set (at least in the encodings that Perl recognizes, and probably
45 * all). But note that the upper bit of some invariants is also 1.
fe749c9a
KW		 46 *
47 * If you're starting from Unicode, skip step 1. For UTF-EBCDIC to straight
48 * EBCDIC, reverse the steps.
49 *
50 * The EBCDIC invariants have been chosen to be those characters whose Unicode
51 * equivalents have ordinal numbers less than 160, that is the same characters
52 * that are expressible in ASCII, plus the C1 controls. So there are 160
53 * invariants instead of the 128 in UTF-8. (My guess is that this is because
54 * the C1 control NEL (and maybe others) is important in IBM.)
55 *
56 * The purpose of Step 3 is to make the encoding be invariant for the chosen
57 * characters. This messes up the convenient patterns found in step 2, so
58 * generally, one has to undo step 3 into a temporary to use them. However,
59 * a "shadow", or parallel table, PL_utf8skip, has been constructed so that for
60 * each byte, it says how long the sequence is if that byte were to begin it
61 *
62 * There are actually 3 slightly different UTF-EBCDIC encodings in this file,
63 * one for each of the code pages recognized by Perl. That means that there
64 * are actually three different sets of tables, one for each code page. (If
d06134e5
KW		 65 * Perl is compiled on platforms using another EBCDIC code page, it may not
66 * compile, or Perl may silently mistake it for one of the three.)
fe749c9a
KW		 67 *
68 * EBCDIC characters above 0xFF are the same as Unicode in Perl's
69 * implementation of all 3 encodings, so for those Step 1 is trivial.
70 *
71 * (Note that the entries for invariant characters are necessarily the same in
72 * PL_e2a and PLe2f, and the same for their inverses.)
73 *
74 * UTF-EBCDIC strings are the same length or longer than UTF-8 representations
75 * of the same string. The maximum code point representable as 2 bytes in
76 * UTF-EBCDIC is 0x3FFF, instead of 0x7FFF in UTF-8.
