   1 The *.txt files were copied from
   2
   3         ftp://www.unicode.org/Public/UNIDATA
   4
   5 with subdirectories 'extracted' and 'auxiliary'
   6
   7 The Unihan files were not included due to space considerations.  Also NOT
   8 included were any *.html files.  It is possible to add the Unihan files, and
   9 edit mktables (see instructions near its beginning) to look at them.
  10
  11 The file 'version' should exist and be a single line with the Unicode version,
  12 like:
  13 5.2.0
  14
  15 To be 8.3 filesystem friendly, the names of some of the input files have been
  16 changed from the values that are in the Unicode DB.  Not all of the Test files
  17 are currently used, so may not be present, so some of the mv's can fail.  The
  18 .html Test files are not touched.

  42 If you have the Unihan database (5.2 and above), you should also do the
  43 following:
  44
  45 mv Unihan_DictionaryIndices.txt UnihanIndicesDictionary.txt
  46 mv Unihan_DictionaryLikeData.txt UnihanDataDictionaryLike.txt
  47 mv Unihan_IRGSources.txt UnihanIRGSources.txt

  51 mv Unihan_Readings.txt UnihanReadings.txt
  52 mv Unihan_Variants.txt UnihanVariants.txt
  53
  54 If you download everything, the names of files that are not used by mktables
  55 are not changed by the above, and will not work correctly as-is on 8.3
  56 filesystems.
  57
  58 mktables is used to generate the tables used by the rest of Perl.  It will warn
  59 you about any *.txt files in the directory substructure that it doesn't know
  60 about.  You should remove any so-identified, or edit mktables to add them to
  61 its lists to process.  You can run
  62
  63     mktables -globlist
  64
  65 to have it try to process these tables generically.
  66
  67 FOR PUMPKINS
  68
  69 The files are inter-related.  If you take the latest UnicodeData.txt, for
  70 example, but leave the older versions of other files, there can be subtle
  71 problems.  So get everything available from Unicode, and delete those which
  72 aren't needed.
  73
  74 When moving to a new version of Unicode, you need to update 'version' by hand
  75
  76         p4 edit version
  77         ...
  78
  79 You should look in the Unicode release notes (which are probably towards the
  80 bottom of http://www.unicode.org/reports/tr44/) to see if any properties have
  81 newly been moved to be Obsolete, Deprecated, or Stabilized.  The full names for
  82 these should be added to the respective lists near the beginning of mktables,
  83 using an 'if' to add them for just this Unicode version going forward, so that
  84 mktables can continue to be used for earlier Unicode versions.
  85
  86 When putting out a new Perl release, think about if any of the Deprecated
  87 properties should be moved to Suppressed.
  88
  89 The code in regexec.c for the \X match construct is intimately tied to the
  90 regular expression in UAX #29 (http://www.unicode.org/reports/tr29/).  You
  91 should see if it has changed, and if so regexec.c should be modified.  The
  92 current one is
  93 ( CRLF
  94 | Prepend* ( Hangul-syllable | !Control )
  95   ( Grapheme_Extend | Spacing_Mark)*
  96 | . )
  97
  98 mktables has many checks to warn you if there are unexpected or novel things
  99 that it doesn't know how to handle.
