I would prefer something a little bit more specific. There are so many possible symmetry cases that we might end up with a full font that contains only harpoons... Lots of the "missing cases" are already in the STIX tables for precisely this reason, but there is just not enough room to capture all possible cases.

This one, for example, is already available (121). But there is no negated version of the left-pointing version while there is a negated version of the "leadsto" (123). Please have a look at the PDF file tomorrow (I'll post one that works with Reader 2.1). Greetings, Taco
