readLine
Removes and returns UTF-8 encoded characters up to but not including the next line break. A line break is either "\n"
or "\r\n"
; these characters are not included in the result.
On the end of the stream this method returns null. If the source doesn't end with a line break, then an implicit line break is assumed. Null is returned once the source is exhausted.
Throws
when the source is closed.
