Follow-up Comment #1, bug #32267 (project screen):
No bug, screen correctly handles both
the seven-bit CSI = " 33133" = ESC [
and eight-bit CSI = "233"
as documented at http://vt100.net/docs/vt220-rm/table4-2.html
and at
http://en.wikipedia.org/wiki/Control_Sequence_Introducer#Sequence_elements
True, octal 233 = hex 9B occurs in many UTF-8 characters, e.g.,
U+00DB LATIN CAPITAL LETTER U WITH CIRCUMFLEX = C3 9B,
U+011B LATIN SMALL LETTER E WITH CARON = C4 9B,
U+015B Latin Small Letter s with Acute = C5 9B, etc.,
but screen should continue to allow the eight-bit CSI
and other eight-bit DEC codes.
Hard to imagine any need to disable this obscure feature.
Peace
