Control: notfound -1 9.53.3~dfsg-8Apologies, I somehow missed the part about pdftotext and the glyph's normal appearance in your original message. I can reproduce that with both files produced by 9.54.0~dfsg-5 but *not* the one produced by 9.53.3~dfsg-8 (attached for reference), using the same pdftotext version (poppler-utils 20.09.0-3.1) for all files.
