Pod::Escapes(3pm)      Perl Programmers Reference Guide      Pod::Escapes(3pm)

NAME
       Pod::Escapes -- for resolving Pod E<...> sequences

SYNOPSIS
         use Pod::Escapes qw(e2char);
         ...la la la, parsing POD, la la la...
         $text = e2char($e_node->label);
         unless(defined $text) {
           print "Unknown E sequence \"", $e_node->label, "\"!";
         }
         ...else print/interpolate $text...

DESCRIPTION
       This module provides things that are useful in decoding Pod E<...>
       sequences.  Presumably, it should be used only by Pod parsers and/or
       formatters.

       By default, Pod::Escapes exports none of its symbols.  But you can
       request any of them to be exported.  Either request them individually,
       as with "use Pod::Escapes qw(symbolname symbolname2...);", or you can
       do "use Pod::Escapes qw(:ALL);" to get all exportable symbols.

GOODIES
       e2char($e_content)
           Given a name or number that could appear in a "E<name_or_num>"
           sequence, this returns the string that it stands for.  For example,
           "e2char('sol')", "e2char('47')", "e2char('0x2F')", and
           "e2char('057')" all return "/", because "E<sol>", "E<47>",
           "E<0x2f>", and "E<057>", all mean "/".  If the name has no known
           value (as with a name of "qacute") or is syntactally invalid (as
           with a name of "1/4"), this returns undef.

       e2charnum($e_content)
           Given a name or number that could appear in a "E<name_or_num>"
           sequence, this returns the number of the Unicode character that
           this stands for.  For example, "e2char('sol')", "e2char('47')",
           "e2char('0x2F')", and "e2char('057')" all return 47, because
           "E<sol>", "E<47>", "E<0x2f>", and "E<057>", all mean "/", whose
           Unicode number is 47.  If the name has no known value (as with a
           name of "qacute") or is syntactally invalid (as with a name of
           "1/4"), this returns undef.

       $Name2character{name}
           Maps from names (as in "E<name>") like "eacute" or "sol" to the
           string that each stands for.  Note that this does not include
           numerics (like "64" or "x981c").  Under old Perl versions (before
           5.7) you get a "?" in place of characters whose Unicode value is
           over 255.

       $Name2character_number{name}
           Maps from names (as in "E<name>") like "eacute" or "sol" to the
           Unicode value that each stands for.  For example,
           $Name2character_number{'eacute'} is 201, and
           $Name2character_number{'eacute'} is 8364.  You get the correct
           Unicode value, regardless of the version of Perl you're using --
           which differs from %Name2character's behavior under pre-5.7 Perls.

           Note that this hash does not include numerics (like "64" or
           "x981c").

       $Latin1Code_to_fallback{integer}
           For numbers in the range 160 (0x00A0) to 255 (0x00FF), this maps
           from the character code for a Latin-1 character (like 233 for
           lowercase e-acute) to the US-ASCII character that best aproximates
           it (like "e").  You may find this useful if you are rendering POD
           in a format that you think deals well only with US-ASCII
           characters.

       $Latin1Char_to_fallback{character}
           Just as above, but maps from characters (like "\xE9", lowercase
           e-acute) to characters (like "e").

       $Code2USASCII{integer}
           This maps from US-ASCII codes (like 32) to the corresponding
           character (like space, for 32).  Only characters 32 to 126 are
           defined.  This is meant for use by "e2char($x)" when it senses that
           it's running on a non-ASCII platform (where chr(32) doesn't get you
           a space -- but $Code2USASCII{32} will).  It's documented here just
           in case you might find it useful.

CAVEATS
       On Perl versions before 5.7, Unicode characters with a value over 255
       (like lambda or emdash) can't be conveyed.  This module does work under
       such early Perl versions, but in the place of each such character, you
       get a "?".  Latin-1 characters (characters 160-255) are unaffected.

       Under EBCDIC platforms, "e2char($n)" may not always be the same as
       "chr(e2charnum($n))", and ditto for $Name2character{$name} and
       "chr($Name2character_number{$name})".
