Method GTK2.TextBuffer()->get_slice()

Method get_slice: string get_slice(GTK2.TextIter start, GTK2.TextIter end, int include_hidden_chars)
Description: Returns the text in the range [start,end). Excludes undisplayed text (text marked with tags that set the invisibility attribute) if include_hidden_chars is false. The returned string includes a 0xFFFC character whenever the buffer contains embedded images, so byte and character indexes into the returned string do correspond to byte and character indexes into the buffer. Contrast with get_text(). Note that 0xFFFC can occur in normal text as well, so it is not a reliable indicator that a pixbuf or widget is in the buffer.
