Actually if I understood the spec, FITS header lines are 80 bytes long and contain ASCII with no NULLs; strings are quoted and trailing spaces are stripped.

FITS BINTABLE extensions can have columns containing strings, and in that case the values are NULL terminated, except that if the string fills the field (i.e. there's no room for a NULL), the NULL will not be written. Phil
