While implementing the encoding argument for fopen, the question arose of
whether the "len" argument of "fgetl" and "fgets" should correspond to the
number of bytes or the number of character entities that are read from an
input stream. This is different for encodings that use multiple bytes to
encode on single character (e.g. non-ASCII characters in UTF-8).
