Or was it really intended (as it appears on the surface) that type 2 lookups for ‘chws’/’vchw’ should be allowed to act on the second glyph but that clients should _exceptionally_ not consume the second glyph in this case?</blockquote><div><br></div><div class="gmail_default" style="font-family:arial,helvetica,sans-serif">Ken knows the text best but I think the answer is the former; there's no intention to add an exceptional behavior.
