International Characters
The 6530 supports two ISO standards used for international characters:
ISO 646 for character sets (including the US ASCII character set)
that comprise 96 7-bit codes.
ISO 8859 for character sets that comprise 256 8-bit codes.
The use of the eighth bit in ISO 8859 character sets enables these sets to
include non-ASCII characters, such as à or ç.
In order to include non-ASCII characters when the 7-bit ISO 646
character set is used, the 6530 utilizes a character substitution method in
which a character in the ASCII set is replaced by one of the characters
from another language. For example, in the English UK character set, the
# character is replaced by the £ character.
Table B-1 lists the codes, the ASCII characters that are replaced, and the
corresponding characters for each supported language that uses the 7-bit
ISO 646 standard.
