What happens when a charged black hole evaporates?

BG: Black holes emit Hawking radiation, as photons, and the smaller the black hole the more it radiates until it finally disappears.

What would happen if you fed a micro black hole electrons to give it a charge, then allowed it to evaporate?  Photons can't carry a charge...  Would some particles be left behind?

Hawking evaporation is not limited to photons.  If a black hole's temperature becomes of order the rest mass of an electron, the black hole can radiate electrons as well, which can carry away the black hole's charge.  

More realistically, however, a highly charged black hole would attract and swallow particles of the opposite charge until it became nearly neutral.
