c# - Are null terminators part of text encoding? -

i'm trying read null terminated string byte array; parameter function encoding.

string readstring(encoding encoding) 

for example, "foo" in following encodings are:

utf-32: 66 00 00 00 6f 00 00 00 6f 00 00 00 utf-8:  66 6f 6f utf-7:  66 6f 6f 2b 41 41 41 2d 

if copied bytes array (reading null terminator) , passed array encoding.getstring(), wouldn't work because if string utf-32 encoded algorithm reach "null terminator" after second byte.

so sort of have double question: null terminators part of encoding? if not, how decode string character character , check following byte null terminator?

thanks in advance

(suggestions appreciated)

edit:

if "foo" null terminated , utf-32 encoded, be?:

1. 66 00 00 00 6f 00 00 00 6f 00 00 00   00 2. 66 00 00 00 6f 00 00 00 6f 00 00 00   00 00 00 00 

the null terminator not "logically" part of string; it's not considered payload. it's used in c/c++ indicate string ends.

having said can have strings embedded \0's have careful ensure string doesn't appear truncated. example std::string doesn't have problem embedded \0's. if c_str() , and not account reported length() string appear cut off.
