String cannot contain embedded nulls?

Just looking at the docs for ModuleBuilder and it's method DefineType which takes a string amongst other parameters.

In the write up it states the parameter 'c开发者_如何学编程annot contain embedded nulls'.

What does that mean?

An example of a string with an embedded null is:

var example = "This is a null: \0";

'\0' is the Unicode character 'NULL' (U+0000).

A string is not null terminated (ends on a null) so therefore you can actually store null characters ('\0') inside of a string. The string you are going to work with cannot have one of these special characters inside it.

Here is Microsoft's definition of string in reference to null characters:
