Reading all buffered bytes without blocking

Is it possible to say to a BufferedReader stream "give me all the bytes you have available in the buffer, or do one OS call and give me everything you get back"? The problem is that the "number of bytes" argument to read1() isn't optional, so I can't do available_bytes = fd.read1().
I need this because I want to decode the returned bytes from UTF-8, and I *might* get a character split across the boundary of any arbitrary block size I choose. (I'm happy to ignore the possibility that the *source* did a flush part-way through a character). I don't really want to have to do incremental encoding if I can avoid it - it looks hard...
Thanks,
Paul
