TrueType PCLT information
TrueType PCL T - The TrueType PCLT entries contain information that may be used on PCL printers. Most of the newer TrueType fonts have this information defined.
UNICODE - The table shows which characters are available in the Lucida Sans Unicode
font. See the appropriate PCL Symbolset tables for examples of the glyphs.
You can find more information on UNICODE on the UNICODE character database web site.
PCL SymbolSet information is only useful when a limited number characters is available. In this case the PCL Symbolset specifies which character codes may be used.
PCL Typeface should be used to in the PCL font selection sequence T code. Note that the PCL driver may not make use of scalable fonts installed on the PC.
