This assumption is not important. You can do the decoding in the process filter, or anywhere else. >> 3 - call decode-coding-region with the appropriate coding system. >> 4 - set the buffer to multibyte. > The buffer comes into being incrementally. There can be several buffers. Remember in point 1 I said "temp buffer".
