Two more thoughts:

a) the incoming data might be UTF-16 or UTF-32. In this case trailing NULs are
2 bytes or 4 bytes, and removing a single NUL byte at the end would might a
character in half. This is an argument for doing the trimming of NULs just
before the gst_utf8_validate() and not earlier.

b) there could be multiple trailing zeroes

So how about a while (len > 0 && str[len-1] == '\0') --len just before the
_validate()?
