It seems to be most probably a bug in ghostscript. A copyright notice in a Type 1 font is just a string. I didn't find anything about limitations in the Type 1 Reference Manual or TN 5015. The PostScript Language Reference Manual (Appendix B) describes PS interpreter requirements. According to this, any PS interpreter should be able to handle strings of least 65535 bytes. There are some restrictions for ATM compatibility but obviously they do not affect string lengths. So I think that ghostscript is the culprit and the bug should be fixed there. Can you send me a small file which shows this problem? At the moment I have 30 different versions of gs installed on my system and it shouldn't bee too difficult to find out which versions are affected (or when this bug had been introduced). > [...] > maybe pdftex can split too long lines into multiple /Copyright > () lines I think that pdftex should remove anything from a font which is not needed, but as far as the copyright notice is concerned, it's certainly best to leave it as it is. Technically, it is wrong to split it into multiple lines. For example: /Copyright (copyright by me.) def /Copyright (you are not allowed to) def /Copyright (give this font away!) def The content of /Copyright is now the string "give this font away!". Even worse, /Copyright is defined as "readonly def". A PS interpreter should complain if someone tries to overwrite the initial definition. I agree with you that the copyright notice is much too long. Nobody spends much time to read so boring stuff, anyway.
