IO

. and , operate on a utf-8 stream. , produces 0 on EOF

: produces a decimal representation of the current cell. ; skips any space (U+20) characters in the input stream and then reads 1 or more ASCII digit (U+30 to U+39), clamps the number to the range [0, 255] and sets the cell to it. If it can't read a digit and EOF has been reached it returns 0, but if EOF hasn't been reached it raises an error flag and stops execution
