16-bit screen-maps:
-----------------
16-bit screen-maps are used when the screen is in 8-bit mode (the default),
to define the character-set used by applications, by telling the kernel how
to interpret these 8-bit chars, in fact by telling to which Unicode character
they should be mapped.
The following files are 16-bit screen maps generated from the file
`UTF-tmpl.8bit', using the `2UTF' program:
iso{01,02..10} ISO 8859 charsets
cp437 IBM codepage 437 (corresponding to the
default PC font)
straight-to-font Maps all application characters directly to
the characters, using the straight-to-font
unicodes.
8-bit screen-maps:
-----------------
8-bit screen maps should be considered obsolete, and should be rewritten as
16-bit maps where needed. They are used to map the charset used by the
application directly to the font in use, bypassing the unicode map describing
the font. Thus, a new 8bit screen-map has to be set each time the font is
changed.
The following are 8-bit screen-maps whose usefulness with current version of
the console driver/tools has to be investigated:
null
space
zero
The following are 8-bit screen-maps which may still be useful to some users,
but, as 8-bit maps, they will bypass the unicode map:
trivial obsoleted by `straight-to-font' (16-bit)
