screen: Character Processing

 
 11.11 Character Processing
 ==========================
 
  -- Command: c1 [state]
      (none)
      Change c1 code processing.  'c1 on' tells screen to treat the input
      characters between 128 and 159 as control functions.  Such an 8-bit
      code is normally the same as ESC followed by the corresponding
      7-bit code.  The default setting is to process c1 codes and can be
      changed with the 'defc1' command.  Users with fonts that have
      usable characters in the c1 positions may want to turn this off.
 
  -- Command: gr [state]
      (none)
      Turn GR charset switching on/off.  Whenever screen sees an input
      char with an 8th bit set, it will use the charset stored in the GR
      slot and print the character with the 8th bit stripped.  The
      default (see also 'defgr') is not to process GR switching because
      otherwise the ISO88591 charset would not work.
 
  -- Command: bce [state]
      (none)
      Change background-color-erase setting.  If 'bce' is set to on, all
      characters cleared by an erase/insert/scroll/clear operation will
      be displayed in the current background color.  Otherwise the
      default background color is used.
 
  -- Command: encoding enc [denc]
      (none)
      Tell screen how to interpret the input/output.  The first argument
      sets the encoding of the current window.  Each window can emulate a
      different encoding.  The optional second parameter overwrites the
      encoding of the connected terminal.  It should never be needed as
      screen uses the locale setting to detect the encoding.  There is
      also a way to select a terminal encoding depending on the terminal
      type by using the 'KJ' termcap entry.  Special
      Capabilities.
 
      Supported encodings are 'eucJP', 'SJIS', 'eucKR', 'eucCN', 'Big5',
      'GBK', 'KOI8-R', 'CP1251', 'UTF-8', 'ISO8859-2', 'ISO8859-3',
      'ISO8859-4', 'ISO8859-5', 'ISO8859-6', 'ISO8859-7', 'ISO8859-8',
      'ISO8859-9', 'ISO8859-10', 'ISO8859-15', 'jis'.
 
      See also 'defencoding', which changes the default setting of a new
      window.
 
  -- Command: charset set
      (none)
      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 a 'encoding' command is active.
 
      The current setting can be viewed with the Info command.
 
  -- Command: utf8 [state [dstate]]
      (none)
      Change the encoding used in the current window.  If utf8 is
      enabled, the strings sent to the window will be UTF-8 encoded and
      vice versa.  Omitting the parameter toggles the setting.  If a
      second parameter is given, the display's encoding is also changed
      (this should rather be done with screen's '-U' option).  See also
      'defutf8', which changes the default setting of a new window.
 
  -- Command: defc1 state
      (none)
      Same as the 'c1' command except that the default setting for new
      windows is changed.  Initial setting is 'on'.
 
  -- Command: defgr state
      (none)
      Same as the 'gr' command except that the default setting for new
      windows is changed.  Initial setting is 'off'.
 
  -- Command: defbce state
      (none)
      Same as the 'bce' command except that the default setting for new
      windows is changed.  Initial setting is 'off'.
 
  -- Command: defencoding enc
      (none)
      Same as the 'encoding' command except that the default setting for
      new windows is changed.  Initial setting is the encoding taken from
      the terminal.
 
  -- Command: defcharset [set]
      (none)
      Like the 'charset' command except that the default setting for new
      windows is changed.  Shows current default if called without
      argument.
 
  -- Command: defutf8 state
      (none)
      Same as the 'utf8' command except that the default setting for new
      windows is changed.  Initial setting is 'on' if screen was started
      with '-U', otherwise 'off'.
 
  -- Command: cjkwidth [state]
      (none)
      Toggle how ambiguoous characters are treated.  If cjkwidth is on
      screen interprets them as double (full) width characters.  If off
      then they are seen as one cell (half) width characters.
