charset set
Change the current character set slot designation and charset mapping.
The first four character of set are treated as charset designators while
the fifth and sixth character must be in range 0 to 3 and set the
GL/GR charset mapping. On every position a '.' may be used to indicate
that the corresponding charset/mapping should not be changed (set is
padded to six characters internally by appending '.' chars). New windows
have “BBBB02” as default charset, unless an encoding
command is active.
The current setting can be viewed with the info command.
