This does not only change the meaning of length, but also null-terminates the string. Is there any reason for that? It doesn't make much sense to both store the length and null-terminate string at the same time. Thanks, Jacek

The FaceName value is stored null-terminated in the registry. It's also null-terminated in the LOGFONTW structure, when copied to the config and in dialogs. We can probably get rid of face_len though.
