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.
