gtk-text-iter-forward-char (iter)

iter -- a gtk-text-iter instance

A boolean whether the iterator moved and is dereferenceable.

Moves the iterator forward by one character offset.

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