Supported Fonts

The set of supported fonts varies between different implementations of the Java 2 platform. This page documents font support in Sun's J2SE Development Kit 5.0 (JDK), and J2SE Runtime Environment 5.0 (JRE). For the terminology used, see the Font class description.

• Support for Physical Fonts
• Support for Logical Fonts
• The Lucida Fonts

Support for Physical Fonts

Sun's J2SE Runtime Environment supports TrueType and PostScript Type 1 fonts.

Physical fonts need to be installed in locations known to the Java runtime environment. Sun's J2SE Runtime Environments look in two locations: the lib/fonts directory within the JRE itself, and the normal font location(s) defined by the host operating system. If fonts with the same name exist in both locations, the one in the lib/fonts directory is used.

Users can add physical fonts that use a supported font technology by installing them either in the lib/fonts directory within the JRE, or by installing them in a way supported by the host operating system (dropping them into the Fonts folder on Windows, using the pkgadd command on Solaris).

Support for Logical Fonts

Logical font names are mapped to physical fonts in implementation dependent ways. Typically one logical font name maps to several physical fonts in order to cover a large range of characters. Sun's J2SE Runtime Environments use font configuration files to define the mapping.

Users can add a physical font as a fallback font to logical fonts used in Java 2D rendering by installing it in the lib/fonts/fallback directory within the JRE.

The Lucida Fonts

Sun's J2SE Development Kit and J2SE Runtime Environments bundle several physical fonts of the "Lucida" design family. These fonts are also licensed for use in other implementations of the Java 2 platform. These fonts are physical fonts, but since they come with the Java 2 runtime, they don't depend on the host operating system. Using them provides the benefit of a consistent look and feel across platforms and implementations for a large set of languages.

There are three different type families: "Lucida Sans", "Lucida Sans Typewriter", and "Lucida Bright". Each family has plain, bold, italic, and bold-italic styles. Not all of these are present in all Java 2 implementations. For example, the default download bundle of Sun's J2SE Runtime Environment for Windows only contains the Lucida Sans plain font (but note that application developers can include all Lucida fonts with a JRE that they redistribute with an application).

The following table shows which Unicode character blocks are covered by each font family:

Unicode Block	Lucida Sans	Lucida Sans Typewriter	Lucida Bright
Basic Latin	yes	yes	yes
Latin-1 Supplement	yes	yes	yes
Latin Extended-A	yes	yes	yes

Note that of the writing systems that are generally fully supported by Sun's J2SE Runtime Environments, the Lucida fonts do not support Chinese (Simplified), Chinese (Traditional), Japanese, and Korean.

The fonts are installed in the J2SE Runtime Environment's lib/fonts directory as the following files (not all of them may be present):

LucidaSansRegular.ttf
