When running essentially your code, I get a missing character message. So the issue here is simply that the box ends up reading "blabla", so the patterns involving ^^^^200D are not relevant. Naively I would expect the pattern to work correctly if your font has this character. Missing character: There is no <U+200D> in font cmr10! Best regards, Bruno
