iter -- a gtk-text-iter instance

True if we moved and the new position is dereferenceable.

Moves the iterator forward by a single cursor position.

Cursor positions are (unsurprisingly) positions where the cursor can appear. Perhaps surprisingly, there may not be a cursor position between all characters. The most common example for European languages would be a carriage return/newline sequence. For some Unicode characters, the equivalent of say the letter "a" with an accent mark will be represented as two characters, first the letter then a "combining mark" that causes the accent to be rendered. So the cursor cannot go between those two characters. See also the pango-log-attr structure and the function pango-default-break.
