NAME

       mapscrn - load screen output mapping table

SYNOPSIS

       mapscrn [-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       The mapscrn command is obsolete - its function is now built-in into setfont.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.

FILES

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