Hamster Font Manager (HFM) helps you control the avaliability of fonts in all of the supported applications from a central place. It includes modules to support X11, Ghostscript, and TeX. A PostScript module handles PS Fonts while other fonts remain untouched by this program. It features a nice Tcl/TK GUI. For X11 configuration to work, this software has to run on the machine's own X Server.
Univert is a Universal Unicode Converter, at least as universal as the Unicode implementation in Tcl 8.1 or later can manage on your computer. Univert will convert interchangably between the following formats: native Tcl unicode, hex bytes or words separated by spaces, decimal bytes or words separated by spaces, HTML entities, UTF-8/URL encoding, quoted printable with whatever the current encoding is, and C string with whatever the current encoding is.
