MAPSCRN(8)                  International Support                 MAPSCRN(8)

NAME         top

       mapscrn - load screen output mapping table

SYNOPSIS         top

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

DESCRIPTION         top

       The mapscrn command is obsolete - its function is now built-in into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         top

       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         top

       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         top
