[mkgmap-dev] typ file editor

Hello, I would like to edit my typ files, but online editor at ati.land.cz is no longer available. As I found it was perl script with BSD license but I cannot find any sources. Does anybody have link to the sources? I have also additional question. Does mkgmap need the typ file to be in the same code page as the map will be? I. E. will it convert the typ file code page to the map code page while creating img file? Thank you Marek
