forward_char

Moves this forward by one character offset.

Note that images embedded in the buffer occupy 1 character slot, so this function 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 this function returns false for convenience when writing loops.

Parameters:

this	an iterator

Returns:

whether this moved and is dereferenceable
