Fix for unicode issue with ConsoleRunner

[adamlehenbauer]

simple fix for multi-byte unicode character issue https://sourceforge.net/tracker/?func=detail&aid=3293355&group_id=64033&atid=506056, feeds bytes to higher-level InputStream instead of chars

this is my attempted fix, I've done basic tests with ConsoleRunner and another application that uses ConsoleReader

I was hoping this would fix non-ASCII characters on Macs with a german keyboard. It doesn't - I still get umlauts read and echoed as "?". Any idea about the cause/fix for that problem?

This is probably because I just used String#getBytes(), which will use the 'platform default' encoding, which appears to be the 'file.encoding' system property, or UTF-8.

I would throw in a System.out.println(sline) around line 94 to ensure that the string is intact there, and then see if specifying an encoding in String#getBytes() fixes it.

I think jline could try to pass around the encodings it pulls in, but those aren't consistent; UnixTerminal uses 'input.encoding' but ConsoleReader uses 'file.encoding'...
