* The "simple" encoding is recommended for TrueType fonts

* The "full" encoding is specially aimed at Type1 fonts where the glyphs have to be
* described by non standard names like the Tex math fonts. Each group of three elements
* compose a code position: the one byte code order in decimal or as 'x' (x cannot be the space), the name and the Unicode character
* used to access the glyph. The space must be assigned to character position 32 otherwise
* text justification will not work.
* <P>
* Example for a "simple" encoding that includes the Unicode
* character space, A, B and ecyrillic:
* <PRE>
* "# simple 32 0020 0041 0042 0454"
