A CID-keyed font is a postscript (or Open Type) font designed to hold Chinese, Japanese and Korean characters efficiently. More accurately a CID font is a collection of several sub-fonts each with certain common features—one might hold all the latin letters, another all the kana, a third all the kanji. CID keyed fonts do not have an encoding built into the font, and the characters do not have names. Instead the font is associated with a character set and on each character set there are several character mappings defined. These mappings are similar to encodings but allow for a wider range of behaviors.
PlanetPress only accepts horizontal fonts and double-byte character set (DBCS) font encodings. In a PPD file, a typical DBCS font is defined as follows:
*Font HeiseiKakuGo-W5-90ms-RKSJ-H: RKSJ "()" 90ms ROM
where:
Font Defines a font
HeiseiKakuGo-W5 Font Name
90ms-RKSJ Encoding type. In this example, the type is RKSJ Japanese. Other language options include: GBK EUC, ETen-B5, Chinese B5, and KSCms-UHC:Korean.
H Specifies whether it is a horizontal font. PlanetPress supports only horizontal fonts and DBCS encodings.
