ESC ) A associates G1 with ISO Latin-1. OK.
SO should then invoke G1 to Left.
But then 7 bit codes do not produce the right ISO-Latin-
1 supplemental characters. Instead they produce
the normal ASCII representation of that 7 bit code.
When using ESC ) < to associate the user preferred
encodeing with G1, which, according to the source,
is also Latin-1, then the right Latin-1 supplemental
characters are produced with 7 bit codes.
I think the cause of this problem is in
jta25b-src.jar/vt320.java:putChar() about line 1470.
case '<' and case 'A' should be handled in the same way.
