Character Set Selection
To make a character set available for printing, you must designate the set as
either G0, G1, G2, or G3. The designated set is then invoked into GL or GR
using single or locking shift, and can be used for printing.
National Replacement Characters (NRCs) are created by replacing the
relevant characters in the U.S. ASCII character set upon receipt of the
appropriate control sequences.
Single and Locking Shifts
A single shift (SS2 or SS3), effects only the first printable GL character
following the single shift sequence (refer to “Special Parsing Requirements,”
page 7–15).
A locking shift (LS2, LS3, LS1R, LS2R, or LS3R) persists until another
locking shift is invoked.
Table 7–16 give the sequences that select the active character sets.
