helper library to store/look-up glyphnames associated to a character code.

Variables

$glyph_names

protected @var $glyph_names an array of arrays with values glyph names and keys unicode codepoints the first index of the array is the encoding type

  • Type: protected $glyph_names

$encoding

  • Type: protected $encoding

$mb_encoding

protected @var string $unicode_encoding

  • Type: protected $mb_encoding

$useMB

  • Type: protected $useMB

$fix

Some common incorrect glyph names

  • Type: static public fix $fix

Methods

get the multibyte character associated to a character code

  • Signature: public function UnicodeFromCharactercode($cc)
  • Returns: int unicode codepoint

Parameters:

  • int $cc
    the character code

UnicodeFromGlyphname()

get the multibyte character associated to a glyphname

  • Signature: public function UnicodeFromGlyphname($gn)
  • Returns: string n character in the selected encoding

Parameters:
