The `set encoding` command selects a character encoding. Valid values are
`default`, which tells a terminal to use its default; `iso_8859_1` (known in
the PostScript world as `ISO-Latin1`), which is used on many Unix workstations
and with MS-Windows; `cp850`, for OS/2; and `cp437`, for MS-DOS.
Syntax:
set encoding {<value>}
show encoding
Note that encoding is not supported by all terminal drivers and that
the device must be able to produce the desired non-standard characters.
