        /// 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".

        /// read from them instead of the name. A name is still required to identify
        /// the font type.

        /// 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:
