Hi Morten, I did open a bug about this sometime ago. The association of parenlefttp with unicode U+F8EB predates the allocation of a proper code in the Miscelaneous Technical block (U+239B). Previously the glyph lived in the Private Use Area of Unicode. The AGL to Unicode mapping used in afmtodit uses the ancient codes, fortunately the mapping in uniglyph.cpp is correct so if you want to use the \[uXXXX] form, this will work. \f[U-S]\[u239B]\f[] And it should look like "⎛". Cheers Deri
