Yes, our laser fonts were created by hand, by Pangolin staff, more than 20 years ago. The laser fonts only have the most common characters. If you type a character that is not in the laser font the software will "substitute" a missing letter from the last TrueType font that was successfully used with the missing characters.
We have worked on technologies that allow single-trace TrueType fonts (which are rare, but do exist). Please contact us directly to see if this would be an acceptable solution for your application.
