/** Creates a new font. This font can be one of the 14 built in types,
* a Type1 font referred to by an AFM or PFM file, a TrueType font (simple or collection) or a CJK font from the
* Adobe Asian Font Pack. TrueType fonts and CJK fonts can have an optional style modifier
* appended to the name. These modifiers are: Bold, Italic and BoldItalic. An
* example would be "STSong-Light,Bold". Note that this modifiers do not work if
* the font is embedded. Fonts in TrueType collections are addressed by index such as "msgothic.ttc,1".
* This would get the second font (indexes start at 0), in this case "MS PGothic".
* <P>
* The fonts may or may not be cached depending on the flag <CODE>cached</CODE>.
* If the <CODE>byte</CODE> arrays are present the font will be
* read from them instead of the name. A name is still required to identify
* the font type.
* <P>
* Besides the common encodings described by name, custom encodings
* can also be made. These encodings will only work for the single byte fonts
* Type1 and TrueType. The encoding string starts with a '#'
* followed by "simple" or "full". If "simple" there is a decimal for the first character position and then a list
* of hex values representing the Unicode codes that compose that encoding.<br>
* The "simple" encoding is recommended for TrueType fonts
* as the "full" encoding risks not matching the character with the right glyph
* if not done with care.<br>
* 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"
* </PRE>
* <P>
* Example for a "full" encoding for a Type1 Tex font:
* <PRE>
* "# full 'A' nottriangeqlleft 0041 'B' dividemultiply 0042 32 space 0020"
* </PRE>
* @param name the name of the font or its location on file
* @param encoding the encoding to be applied to this font
* @param embedded true if the font is to be embedded in the PDF
* @param cached true if the font comes from the cache or is added to
* the cache if new, false if the font is always created new
* @param ttfAfm the true type font or the afm in a byte array
* @param pfb the pfb in a byte array
* @param noThrow if true will not throw an exception if the font is not recognized and will return null, if false will throw

* This parameter is useful for FontFactory that may have to check many invalid font names before finding the right one

* can also be made. These encodings will only work for the single byte fonts
* Type1 and TrueType. The encoding string starts with a '#'
* followed by "simple" or "full". If "simple" there is a decimal for the first character position and then a list
* of hex values representing the Unicode codes that compose that encoding.<br>
* The "simple" encoding is recommended for TrueType fonts
* as the "full" encoding risks not matching the character with the right glyph
* if not done with care.<br>
* 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"
* </PRE>
* <P>
* Example for a "full" encoding for a Type1 Tex font:
* <PRE>
* "# full 'A' nottriangeqlleft 0041 'B' dividemultiply 0042 32 space 0020"
* </PRE>
