Jon offered opinions about PUA and conformance and was gracious enough to indicate that it was opinion. Here's my take, FWIW: Any application which bans or prevents the interchange or storage of PUA code points should be considered non conformant. Any application which substitutes missing glyphs for PUA characters, when a valid font which covers those code points is active, should be considered non conformant. Like it or not, the PUA is part of Unicode. It's a free zone, and the *only* restriction on its use is that TUC will never assign characters in the PUA ranges. Since the PUA is for consenting adults, any application which restricts PUA use is effectively precluding consenting adults from reaching and implementing their private agreements. We should never allow those who disdain the PUA to determine its boundaries. Best regards, James Kass .
