TextIter.forwardChar

Moves iter forward by one character offset. Note that images embedded in the buffer occupy 1 character slot, so [gtk.text_iter.TextIter.forwardChar] may actually move onto an image instead of a character, if you have images in your buffer. If iter is the end iterator or one character before it, iter will now point at the end iterator, and [gtk.text_iter.TextIter.forwardChar] returns false for convenience when writing loops.
