The starter code is a cleaned up version from the videos:

The task for this week is to fill in the function bytes_for(char* unicode, unsigned int n).
That function should take a UTF-8 string and a character count, and return the number of bytes in that UTF-8 string taken up by the first n characters.
Examples:
bytes_for("José", 3) -> 3
bytes_for("Ülo", 3) -> 4
bytes_for("José", 4) -> 5
bytes_for("成龙", 1) -> 3
bytes_for("成龙", 2) -> 6
bytes_for("成龙", 3) -> -1
