CODEPAGE ENCODING
Since ancient computers are displaying text as 8-bit characters due to the
design of early video adapters, AMA files are expected to contain 8-bit text
as well. The exact codepage is unspecified by this format definition and
depends on the document's target audience.
To ease displaying of AMB books on modern (unicode-enabled) platforms, any AMB
file that contains non-7-bit characters SHOULD also contain a file named
"unicode.map". This file contains a sequence of 128 16-bit values, mapping
bytes of the range 128..255 into unicode datapoint values. Such file can be
readily output by the utf8tocp program <http://utf8tocp.sourceforge.net>.
