NAME

       mapscrn - load screen output mapping table

SYNOPSIS

       mapscrn [-V] [-v] [-o map.orig] mapfile

DESCRIPTION

       The  mapscrn  command  is  obsolete  - its function is now built-in into setfont.  However, for backwards
       compatibility it is still available as a separate command.

       The mapscrn command loads a user defined output character mapping table  into  the  console  driver.  The
       console  driver  may be later put into use user-defined mapping table mode by outputting a special escape
       sequence to the console device.  This sequence is <esc>(K for the G0 character set and <esc>)K for the G1
       character set.  When the -o option is given, the old map is saved in map.orig.

USE

       There  are  two  kinds  of mapping tables: direct-to-font tables, that give a font position for each user
       byte value, and user-to-unicode tables that give a unicode value for each user  byte.  The  corresponding
       glyph is now found using the unicode index of the font.  The command
              mapscrn trivial
       sets  up a one-to-one direct-to-font table where user bytes directly address the font. This is useful for
       fonts that are in the same order as the character set one uses.  A command like
              mapscrn 8859-2
       sets up a user-to-unicode table that assumes that the user uses ISO 8859-2.

INPUT FORMAT

       The mapscrn command can read the map in either of two formats:
       1. 256 or 512 bytes binary data
       2. two-column text file
       Format (1) is a direct image of the translation table.  The  256-bytes  tables  are  direct-to-font,  the
       512-bytes  tables are user-to-unicode tables.  Format (2) is used to fill the table as follows: cell with
       offset mentioned in the first column is filled with the value  mentioned  in  the  second  column.   When
       values larger than 255 occur, or values are written using the U+xxxx notation, the table is assumed to be
       a user-to-unicode table, otherwise it is a direct-to-font table.

       Values in the file may be specified in one of several formats:
       1. Decimal: String of decimal digits not starting with '0'
       2. Octal: String of octal digits beginning with '0'.
       3. Hexadecimal: String of hexadecimal digits preceded by "0x".
       4. Unicode: String of four hexadecimal digits preceded by "U+".
       5. Character: Single character enclosed in single quotes. (And the binary  value  is  used.)   Note  that
       blank, comma, tab character and '#' cannot be specified with this format.
       6. UTF-8 Character: Single (possibly multi-byte) UTF-8 character, enclosed in single quotes.

       Note that control characters (with codes < 32) cannot be re-mapped with mapscrn because they have special
       meaning for the driver.

OTHER OPTIONS

       -V     Prints version number and exits.

       -v     Be verbose.

FILES

       /usr/share/consoletrans is the default directory for screen mappings.
