Please check if this small code snippet looks correct

As I'm new to all this, I want to make sure this is the right way to 
create a scalar value containing a single arbitrary unicode codepoint, 
in utf8.  uv is a UV containing the ordinal value to store.

U8 string[UTF8_MAXBYTES+1];
U8 *tmps;
SV *sv_str;

tmps = uvuni_to_utf8(string, uv);
sv_str = newSVpvn_utf8((char*)string, tmps - string, TRUE);


I believe this works even if the code point is NUL.

thanks
