TLFTypographicCase.LOWERCASE_TO_SMALL_CAPS

Question

I have a web app which uses TLF to render text. I'm having an issue with TLFTypographicCase.LOWERCASE_TO_SMALL_CAPS.
Simply put: It does not seem to work correctly. I'm getting that exact same results using TLFTypographicCase.LOWERCASE_TO_SMALL_CAPS as I get using TLFTypographicCase.UPPERCASE.
It seems to me that the lowercase is being converted to uppercase, but not to small caps. I have a similar problem with TLFTypographicCase.CAPS_TO_SMALL_CAPS. The result is exactly the same as TLFTypographicCase.DEFAULT.
The font I tested with was Poplar Std. I'm using Flex 4.5.0.
It looks to me that the Adobe help page has the same problem: http://help.adobe.com/en_US/flex/using/WS02f7d8d4857b1677-165a04e1126951a2d98-7ff0.html
Notice that the "T" and the "H" are the same size. The text is being rendered as all caps instead of small caps.

Answer 1

In fact, relying on c2sc or smcp is a broken implementation in my book.
The way it SHOULD work is like this:
If smcp or c2sc is defined great. Otherwise, in should look in the font for the small cap glyphs in the correct unicode positions and use those glyphs if they are defined...
Of course fake small caps would be great as well, but at the very least, the predefined glyphs should be used. (Arial DOES have the small caps unicode positions defined.)
