If some substitution is performed, it entails mapping from one or more input characters denoting textual character information to one or more output character codes denoting glyphs in this font, where the output character codes may make use of private character code values that have significance only for this font.

  Specified by:

  performSubstitution in interface Substitutable

  Parameters:

  charSequence - character sequence to map to output font encoding character sequence

  script - a script identifier

  language - a language identifier

  associations - optional list to receive list of character associations

  retainControls - if true, then retain control characters and their glyph mappings, otherwise remove

  Returns:

  output sequence (represented as a character sequence, where each character in the returned sequence denotes "font characters", i.e., character codes that map directly (1-1) to their associated glyphs

In the case of LTR segments, marks are not reordered by this, method since when the segment is reversed by BIDI processing, marks are automatically reordered to precede their base character.

  Specified by:

  reorderCombiningMarks in interface Substitutable

  Parameters:

  cs - character sequence within which combining marks to be reordered

  gpa - associated glyph position adjustments (also reordered)

  script - a script identifier
