forward_cursor_position

Moves this 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 can’t go between those two characters.

See also the [struct@Pango.LogAttr] struct and the [func@Pango.break] function.

Parameters:

this	a `GtkTextIter`

Returns:

true if we moved and the new position is dereferenceable
