It is called STRING_SET_CHARS because it sets the same member that
SCHARS returns.  And CHARS is actually correct, because the 'size'
member counts string characters (as opposed to bytes).  So I don't
think there's a problem with the name here, you just need ti get used
to thinking about it as 'chars', not 'size'.
