Obtains an iterator pointing to byte_index
within the given line.
byte_index
must be the start of a UTF-8 character. Note bytes, not characters; UTF-8 may encode one character as multiple
bytes.
Before the 3.20 version, it was not allowed to pass an invalid location.
Since the 3.20 version, if line_number
is greater than the number of lines in the this,
the end iterator is returned. And if byte_index
is off the end of the line, the iterator at the end of the line is returned.
