TextBuffer.insertChildAnchor

Inserts a child widget anchor into the text buffer at iter. The anchor will be counted as one character in character counts, and when obtaining the buffer contents as a string, will be represented by the Unicode “object replacement character” 0xFFFC. Note that the “slice” variants for obtaining portions of the buffer as a string include this character for child anchors, but the “text” variants do not. E.g. see [gtk.text_buffer.TextBuffer.getSlice] and [gtk.text_buffer.TextBuffer.getText]. Consider [gtk.text_buffer.TextBuffer.createChildAnchor] as a more convenient alternative to this function. The buffer will add a reference to the anchor, so you can unref it after insertion.
