gtk:text-iter-inside-sentence (iter)

iter -- a gtk:text-iter instance

True if the iterator is inside a sentence.

Determines whether the iterator is inside a sentence, as opposed to in between two sentences, for example, after a period and before the first letter of the next sentence. Sentence boundaries are determined by Pango and should be correct for nearly any language, if not, the correct fix would be to the Pango text boundary algorithms.
