The ClearlyU family of bitmap fonts provides a set of 12 pt, 100 dpi proportional BDF fonts with many of the glyphs needed for Unicode text (including numerous alternate glyphs and other glyphs not encoded in Unicode that are necessary to actually display certain scripts, e.g., Arabic or Devanagari).
The DejaVu fonts are a font family based on the Bitstream Vera Fonts. Its purpose is to provide a wider range of characters while maintaining the original look and feel. The family is available as TrueType fonts and also as third-party packages for various operating systems, including handhelds.
FIGlet is a program for making large letters out of ordinary text. It prints its input using large characters made up of ordinary screen characters. FIGlet output is generally reminiscent of the sort of "signatures" many people like to put at the end of email and UseNet messages. It is also reminiscent of the output of some banner programs, although it is oriented normally, not sideways.
FONTpage is a utility for viewing, managing, and generating images of fonts. It can install and delete per-user fonts as well as (when run as root) system-wide fonts. It displays fonts, has a full alpha-numeric popup window, and allows you to change the font size and color, background color, font face, bold, and italics. It also has the ability to input the text to be displayed, which you can choose to save as a PNG file. It is handy to view fonts and styles quickly, or to make "logo" graphics. And naturally, it is a simple way to try out fonts without dipping into the command line. The source code as well as Slackware packages are available.
Fluxfont is a specialized tool that attempts to tackle the privacy concerns raised by the possibility to collect information about the fonts installed on a system. Such information can be used to uniquely identify a system. With Fluxfonts, new fonts are randomly created and removed to prevent the same fingerprint from being recreated.
Font Collector collects fonts in many PalmOS font formats and converts them to a number of other formats. This allows use of pre-OS5 fonts on OS5 units and vice versa, and many other things. It requires PalmOS 3.5 or later. Supported inputs include fonts hidden within applications, Fonts4OS5, FontSubst, FontHackV, Fonthack, iSilo, PalmBible+, Plucker, Font Bucket, and system fonts. Supported outputs include Fonts4OS5, FonFontSubst, FontHackV (these three only under OS5), PalmBible+, Plucker, iSilo, Mobipocket, and Fonthack. The freeware version works for PalmBible+, Plucker, and iSilo output. The shareware version works for all other outputs.
Font Industry (字体工业) makes big charset font creation easier. The program converts a scanned in grid sheet, containing a lot of glyphs, into a bitmap font. The glyphs will be automatically indexed by Unicode or with a user-selected charset order. The bitmap font can then be converted to an outline font like TTF or OpenType font.
Font Manager is a font management application for the GNOME desktop. It is not intended to be a professional-grade font management solution, but rather a simple application suitable for the needs of most desktop users and even some graphics designers who may need to manage just a few thousand font files. Although designed with the GNOME desktop environment in mind, it should work well with most major desktop environments such as XFCE, Enlightenment, and KDE.
