The socket bind is both missing the parameter check and is passing '&' when the variable is already a pointer.

The f_utf_character_to_char() is a mess.
Not sure what I was trying to do, but it is clearly wrong.
Redesign it to be more correct but I should revisit this for a more thorough review.
There are endianess situations that also need resolved so I added an @todo.
