Chapter 11
Character Set, Fonts and Bar Codes
This chapter contains the various single-byte character sets, that
can be selected using the
NASC
statement. Double-byte character
sets are not included, but are available separately on special request.
The following information applies to all single-byte character sets:
•
Characters between ASCII 0 decimal and ASCII 31 decimal are
unprintable control characters as listed below.
•
Characters between ASCII 32 decimal and ASCII 127 decimal
can always be printed, regardless of 7-bit or 8-bit communica-
tion protocol, provided that the selected font contains the char-
acters in question.
•
Characters between ASCII 127 decimal and ASCII 255 deci-
mal can only be printed if the selected font contains the charac-
ters in question and an 8-bit communication protocol is used. If
you use 7-bit communication, select another national character
set (see
NASC
statement in chapter 6.11) or use a
MAP
state-
ment to remap a character set (see chapter 6.10).
•
If a character, which does not exist in the selected font, is used,
a space will be substituted in a Speedo font, and an empty rec-
tangle in a TrueType font.
