Why should we, as Python programmers, care one whit about ASCIIZ strings?
They're not relevant. You might as well say that file names cannot
contain the character "π" because ASCIIZ strings don't support it.
No they don't, and yet nevertheless file names can and do contain
characters outside of the ASCIIZ range.
Under Linux, a file name contains bytes, most commonly representing
UTF-8 sequences. So... an ASCIIZ string *can* contain that character,
or at least a representation of it. Yet it cannot contain "\0".
I've seen a variation of UTF-8 that encodes U+0000 as 2 bytes so that a
zero byte can be used as a terminator.
It's therefore not impossible to have a version of Linux that allowed a
(Unicode) "\0" in a filename.
