Assuming there's a good reason, such as monster lines, not to just read
the next line anyway, I'd suggest read()ing the next character then
seek()ing back by one character to restore the file position.
def peekChar(fileobj):
ch = fileobj.read(1)
fileobj.seek(-1,1)

and you can convert them all to strings. Just remember that you can work
