mapscrn - load screen output mapping table
mapscrn [-V] [-v] [-o map.orig] mapfile
The mapscrn command is obsolete - its function is now built-in into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.
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.
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.
-V Prints version number and exits.
-v Be verbose.
@DATADIR@/consoletrans is the default directory for screen mappings.
