Adds a copy of the first len bytes of string to the GStringChunk.
The copy is nul-terminated.
Since this function does not stop at nul bytes, it is the caller's
responsibility to ensure that string has at least len addressable
bytes.
The characters in the returned string can be changed, if necessary,
though you should not change anything after the end of the string.
Since 2.4
