Reencoding

Source TrueType fonts can have the following encodings:

1. Normal Unicode encoding. In this case all characters are assigned to

their proper Unicode indexes. This makes it very easy to determine to

which languages they belong and how they can be used.

2. Normal Symbol encoding. The codes in the 0-255 range are mapped to

symbolic or pictorial characters.

3. Simulated Symbol encoding. Symbol encoding is used to map normal

alphabet characters of a language to the 0-255 codes.

4. Simulated Unicode encoding. Unicode indexes of the Latin language

are used to map characters of some other language to the 0-255 codes.

Only encodings 1 and 2 (normal Unicode and Symbol) give full information

about mapping codes to characters. All other cases require you to make

some additional definition(s). You must tell TransType which encoding is

simulated by the Symbol or Latin Unicode indexes. When TransType gets

this information from you it can assign proper Unicode indexes to

characters and treat this font as a case 1 in our list. Using this method we

can limit the number of potential source encoding configurations to two:

Unicode and Symbol.
