The fonts are cached and if they already exist they are extracted from the cache, not parsed again.
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.
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.
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.
Example for a "simple" encoding that includes the Unicode character space, A, B and ecyrillic:
"# simple 32 0020 0041 0042 0454"
Example for a "full" encoding for a Type1 Tex font:
"# full 'A' nottriangeqlleft 0041 'B' dividemultiply 0042 32 space 0020"
