You could go the Octavia Butler route and check out the ooloi stuff. I don't remember how they referred to themselves, or how others referred to them, but I'm pretty sure it was "it." It was the third sex. There was male, female, and ooloi. Him, her, it.
Also, the facewrap thing - I give you exhibit A:
The buxom, curvy woman.
Wearing a facewrap.
And a bra.
And a tight pair of pants.
The code should hide the fact that it's a female just because she's covering the bottom half of her face? Seriously?
And don't suppose that this is an isolated incident. There lots of buxom, or curvy, or wide-hipped, or otherwise OBVIOUSLY female-written PCs in the game. Often. The code should absolutely positively NOT hide their gender just because the lower half of their face is covered. If they're wearing a cloak, then the cloak is obscuring the most obvious features. If they're wearing a cowl - it isn't obscuring them and I don't think those should hide their gender either.
Things that cover the head, but not the rest of the body, should NOT hide gender.
