From "man xterm":

Modes for setting keyboard style:

8-Bit Controls (8-bit-control)

Enabled for VT220 emulation, this controls whether xterm will send 8-bit control sequences rather than using 7-bit (ASCII) controls, e.g., sending a byte in the range 128-159 rather than the escape character followed by a second byte. Xterm always interprets both 8-bit and 7-bit control sequences (see the document Xterm Control Sequences). This corresponds to the eightBitControl resource.

(Xterm Control Sequences is the document to which you linked earlier.)

But for some reason, the 8-bit control sequence I posted above isn't recognised by my xterm.

Ideally, it would recognise the sequences only between characters, but maybe it's detecting the sequences in the middle of characters too.

    While a raw 0x9B doesn't work on my (non-xterm) console, the UTF-8 encoding of 0x9B works! 

    # Doesn't work
perl -we'print "\x9B31m", "foo", "\x9B0m", "bar", "\n";'

# Works
perl -CS -we'print "\x9B31m", "foo", "\x9B0m", "bar", "\n";'

    Neither work on in an xterm for me.
