then it is decoded from that same coding system.
-The noninteractive arguments are START, END, COMMAND, OUTPUT-BUFFER, REPLACE,
-ERROR-BUFFER. If REPLACE is non-nil, that means insert the output
-in place of text from START to END, putting point and mark around it.
-Noninteractive callers can specify coding systems by binding
-`coding-system-for-read' and `coding-system-for-write'.

If the output is one line, it is displayed in the echo area,

In either case, the output is inserted after point (leaving mark after it).

+If optional fifth sixth ERROR-BUFFER is non-nil, it is a buffer

If it is nil, error output is mingled with regular output."
