mapscrn - load screen output mapping table
] [-o map.orig
command is obsolete - its function is now built-in into
setfont. However, for backwards compatibility it is still available as a
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
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
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
sets up a user-to-unicode table that assumes that the user uses ISO 8859-2.
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
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:
String of decimal digits not starting with '0'
String of octal digits beginning with '0'.
String of hexadecimal digits preceded by "0x".
String of four hexadecimal digits preceded by "U+".
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
because they have special meaning for the driver.
