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 prompted by 2BFF 1 HELLSCHREIBER PAUSE SYMBOL in the pipeline, although I learned about both earlier today within a few minutes of one another. Thanks, Leo
