createMap
public static CMap createMap(short format, short language)
Create a map for the given format and languageThe Macintosh standard character to glyph mapping is supported by format 0.
Format 2 supports a mixed 8/16 bit mapping useful for Japanese, Chinese and Korean.
Format 4 is used for 16 bit mappings.
Format 6 is used for dense 16 bit mappings.
Formats 8, 10, and 12 (properly 8.0, 10.0, and 12.0) are used for mixed 16/32-bit and pure 32-bit mappings.
This supports text encoded with surrogates in Unicode 2.0 and later.Reference:
