## 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       The  **mapscrn**  command  is obsolete - its function is now built-in into setfont.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 out‐
       putting 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 di‐
       rect-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.
