MARC::Charset::Code(3pm)				User Contributed Perl Documentation				  MARC::Charset::Code(3pm)

NAME

       MARC::Charset::Code - represents a MARC-8/UTF-8 mapping

SYNOPSIS

DESCRIPTION

       Each mapping from a MARC-8 value to a UTF-8 value is represented by a MARC::Charset::Code object in a MARC::Charset::Table.

METHODS

   new()
       The constructor.

   name()
       A descriptive name for the code point.

   marc()
       A string representing the MARC-8 bytes codes.

   ucs()
       A string representing the UCS code point in hex.

   charset_code()
       The MARC-8 character set code.

   is_combining()
       Returns true/false to tell if the character is a combining character.

   to_string()
       A stringified version of the object suitable for pretty printing.

   char_value()
       Returns the unicode character. Essentially just a helper around ucs().

   marc_value()
       The string representing the MARC-8 encoding.

   charset_name()
       Returns the name of the character set, instead of the code.

   to_string()
       Returns a stringified version of the object.

   marc8_hash_code()
       Returns a hash code for this Code object for looking up the object using MARC8. First portion is the character set code and the second is
       the MARC-8 value.

   utf8_hash_code()
       Returns a hash code for uniquely identifying a Code by it's UCS value.

   default_charset_group
       Returns 'G0' or 'G1' indicating where the character is typicalling used in the MARC-8 environment.

   get_marc8_escape
       Returns an escape sequence to move to the Code from another marc-8 character set.

   charset_value
       Returns the charset value, not the hex sequence.
