RE: ATSUI Smart Font quote mangling

In an earlier email I remarked how when you draw letters one at a time, the string like "can't" will generate a left curved quote character in most fonts instead of the apostrophe character. This glyph remapping is a font property, and some well intentioned person claimed in a previous email that kAllTypographicFeaturesOffSelector in the style run would turn off this smart quote feature. I can assure you that that flag has no effect on the apostrophe into quote problem. Certain fonts appear to have state machines inside, and the worst offender of all is the Apple Chancery font, which when drawn one letter at a time uses fancy swashes whether you want them or not, and you cannot turn it off.

These were bad design decisions on Apple's part to do all sorts of glyph remapping without letting the caller control it in any way, and assumed that lines of text were always drawn a line at a time. It makes it extremely hard to do you own custom letter arrangement, when glyphs are remapping "under the table".

Somebody always throws up arabic as a reason why things should be done a certain way, frankly we aren't concerned with arabic, and would like English to work first properly.
