Per Unicode specification, U+06E6 is a Letter Modifier, not a Nonspacing Mark. Common font production workflows cause the advancewidth of nonspacing marks to be set to zero, making this character unusable for its intended purpose.
Also, it is not "below" in any sense so, following the pattern of U+06E5, I suggest it should be named yehSmall-ar rather than yehbelow-ar. The latter is included in the altNames attribute for backwards compatibility.
