True, C strings can't contain a null byte other than the terminating
byte, so, since they can't contain a(ny other) null byte, they can't
represent the character NUL/NULL (in ASCII or standard UTF-8 encoding).

However, make sure you don't neglect to handle the fact that that a 
UTF-8 input stream (just link an ASCII input stream), can contain a 
null byte (representing a NULL character).  

(I don't know if this mailing list deals only with files in general
(which could contain null-byte representations of NULL characters)
or deals with restricted strings (e.g., strings used to name files,
which strings are defined to never contain a NULL character).)
