You can write an arbitrary byte string to text or binary files, and you
can write ASCII (or EBCDIC or UTF16) strings to text or binary files.
Depending on your system, it might end convert some bytes in text mode.
There is nothing that will reach out and smack your C program, though
it might smack some of the bytes going out. It really is system specific.

If you stick to text mode with isprint() characters together with "\n"
and "\t", and don't assume fseek/ftell are byte offsets, you should
be compatiable with all other plain text processing programs on your
machine, and any other system with the same character set and character
encoding. There will also be character set convertors available.
