NAME
    Font::TTF::OldCmap - Character map table

    This module is deprecated

DESCRIPTION
    Looks after the character map. The primary structure used for handling a cmap is the
    Font::TTF::Segarr which handles the segmented arrays of format 4 tables, and in a simpler form
    for format 0 tables.

    Due to the complexity of working with segmented arrays, most of the handling of such arrays is
    via methods rather than via instance variables.

    One important feature of a format 4 table is that it always contains a segment with a final
    address of 0xFFFF. If you are creating a table from scratch this is important (although
    Font::TTF::Segarr can work quite happily without it).

INSTANCE VARIABLES
    The instance variables listed here are not preceded by a space due to their emulating structural
    information in the font.

    Num Number of subtables in this table

    Tables
        An array of subtables ([0..Num-1])

    Each subtables also has its own instance variables which are, again, not preceded by a space.

    Platform
        The platform number for this subtable

    Encoding
        The encoding number for this subtable

    Format
        Gives the stored format of this subtable

    Ver Gives the version (or language) information for this subtable

    val This points to a Font::TTF::Segarr which contains the content of the particular subtable.

METHODS
  $t->read
    Reads the cmap into memory. Format 4 subtables read the whole subtable and fill in the segmented
    array accordingly.

    Format 2 subtables are not read at all.

  $t->ms_lookup($uni)
    Given a Unicode value in the MS table (Platform 3, Encoding 1) locates that table and looks up
    the appropriate glyph number from it.

  $t->find_ms
    Finds the Microsoft Unicode table and sets the "mstable" instance variable to it if found.
    Returns the table it finds.

  $t->out($fh)
    Writes out a cmap table to a filehandle. If it has not been read, then just copies from input
    file to output

  @map = $t->reverse([$num])
    Returns a reverse map of the table of given number or the Microsoft cmap. I.e. given a glyph
    gives the Unicode value for it.

BUGS
    *   No support for format 2 tables (MBCS)
