Removing hidden notices in type 1 files
Some foundries like Linotype and LetterPerfect have started placing notices in fonts at the time you run the "exe" installation executable. These notices appear in the encrypted part of the font and contain up to five computer identification numbers of computers on your network at the time of installation. I guess it is in preparation for future Microsoft software to disable the use of fonts except on computers they were originally installed on. The plan was (is?) to let you contact a company and pay some fixed amount if you wanted to use the font on another computer. Hackers on UNIX can easily remove these notices. First get the t1utils package. You will need t1asm, t1disasm and t1binary from this package. On a pfb file, run t1disasm to obtain an ascii file. Look for "eexec", and remove all lines starting with % or any number of blanks followed by % between eexec and the end of the file. Then run t1asm to get a pfa file, and t1binary to obtain a pfb file. Bingo. It is a piece of cake to write a script for this. The afm files are typically clean. |
