forward_char

Moves this forward by one character offset.

Note that images embedded in the buffer occupy 1 character slot, so forward_char may actually move onto an image instead of a character, if you have images in your buffer. If this is the end iterator or one character before it, this will now point at the end iterator, and forward_char returns false for convenience when writing loops.

Parameters:

this	an iterator

Returns:

whether this moved and is dereferenceable
