Title: No representation for usual ZERO-WIDTH chars

ZWNJ is so common in Persian texts, and its unicode bi-direction class in neutral.
But the representation chunk contains latin characters and are so left-to-right.
So, when ZWNJ is replaced by the representation chunk, rtl texts are rendered incorrectly.

ZWJ and ZWSP are from the same class, but less common at least in Persian texts.
