If, as I suspect, there is a mismatch between Tcl's selection and kterm,
that might be the LAST resort.

Boo-boo. I thought I was looking at ICCCM codes when I saw these funny
thingos showing up in some snap dumps I did by passing the selection to
a C routine. Then I worked out how to print out binary field contents in
Tcl (no mean feat, as everything is in UTF8-coded strings), and it turned
out they were strings of EUC-JP, but Tcl had helpfully transformed each
byte of the EUC to UTF8 before passing it to the C module.

Well, kterm is handing in EUC, but with the first two bytes missing.
Yudit is now handing in Unicode codepoints in a "\unnnn" format.

The only ISO-2022 style I am seeing has the long shift-in sequence, and
no closure at all.

I felt like a script kiddy, who'd just released his first virus.
