Adobe Postscript Type 1 fonts: A single-byte
font type designed for Roman language fonts; one of the earliest
cross-platform (Macintosh and Windows) fonts. These fonts consist
of an outline font file and an Adobe font metrics (AFM) file. On
Linux systems, the outline file must be a printer font ascii (.pfa)
file, not a printer font binary (.pfb) file
as on Windows machines.
TrueType fonts: A widely used cross-platform
font format, easily installed on Linux systems.
CID (Character ID) fonts: A multi-byte
adaptation of Adobe Postscript® Type 1 fonts, well-suited to representing the
large character sets of Asian languages such as Japanese, Korean,
and Chinese.
OpenType® fonts: A cross-platform font developed jointly
by Adobe and Microsoft®,
supporting expanded character sets and layout features such as the
euro currency symbol and the broad range of accented characters
required by eastern European languages.
