Xcyr-fonts is a package of Cyrillic screen fonts for X, suitable for Belorussian, Bulgarian, Macedonian, Russian (new and old orthography), Serbian, Ukrainian languages. They are encoded using a new map KOI8-C that coincides with the standard KOI8-(R,U) in the letters area but adds more Cyrillic letters (all of ISO8859-5 plus Yat', Fita, Izhitsa) and some typographic symbols (mostly from CP-1251). The font set is a fully compatible superset of the standard XFree86 Russian Cyrillic fonts, with numerous changes to improve quality.
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).
Alphabet Soup is a project which attempts to determine a number of things about the shapes of letters in several different writing systems. First, it hypothesizes a set of basic building blocks that all letters are built up from. Second, it hypothesizes a set of rules, a grammar or syntax, which defines how those pieces combine to make different letters. It can generate individual letters, randomize letters in an input string to create weird but readable text, or generate random strings of symbols.
The ucs-fonts package contains versions of all the "-misc-fixed-*" and Adobe X Window System bitmap fonts which have been extended to the largest possible Unicode subset that is sensible for these font sizes. These fonts are commonly used with xterm and many other applications. This package also includes a tool to convert these Unicode fonts into other encodings, such as the many ISO 8859 sets.
The pfbtopfa utility converts PostScript Type 1 fonts in the PFB binary format into the ASCII PFA format used by X and other Unix PostScript Type 1 font uses. It can be used to convert font files, or it can be used as a traditional Unix filter, reading its input from stdin and writing its output to stdout. It can also be used as a combination of the two: read from stdin, write to a file, or read from a file, write to stdout.
acoc is a regular-expression based colour formatter for programs that display output on the command-line. It works as a wrapper around the target program, executing it and capturing the stdout stream. Optionally, stderr can be redirected to stdout, so that it, too, can be manipulated. acoc then applies matching rules to patterns in the output and applies colours to those matches.
rxvt-unicode is a clone of the well known terminal emulator rxvt, modified to store text in Unicode and to use locale-correct input and output. It also supports mixing multiple fonts at the same time, including Xft fonts, real transparency, and an optional embedded Perl interpreter that allows you to extend your terminal easily.
