Wikipedia (https://en.wikipedia.org/wiki/IBM_1620#Invalid_character)
describes the "invalid character" symbol (see attachment) as a Cyrillic Ж
which it obviously is not.
But what is it? Does it deserve encoding, or is it a glyph variation of an
existing codepoint?
The question is somewhat prompte

The glyph there looks more like U+1D219 Greek vocal notation symbol-51:

than a Ж.
If it was implemented as an overprint, either )^H|^H( or \^H|^H/ and was
intended to signify an invalid character
