FontForge is an outline font editor that lets you create your own postscript, truetype, opentype, cid-keyed, multi-master, cff, svg and bitmap (bdf, FON, NFNT) fonts, or edit existing ones. It also lets you convert one format to another. FontForge has support for many Macintosh font formats. From the README-unix file inside the source: If you want to edit CID-keyed fonts (for CJK fonts) you may want to pull down the cidmap package from http://fontforge.sf.net/cidmaps.tgz We have included it with our tarball, but you might want to check for a newer version just in case. If you have it in the directory with the SlackBuild script, it will automatically place the cidmaps inside the package. You will also want to have an extracted copy of the freetype source code available inside the extracted SlackBuild tarball directory - in other words: /somedir/fontforge/ README fontforge.SlackBuild fontforge.info slack-desc freetype-2.3.7/ Fontforge seems to build (and function) just fine without doing this (this is at least true for prior versions), but it does look for the freetype sources while compiling, so it's probably best to make them available just in case :)
