These are two different questions, but both refer to the shape of some glyphs.
1) The U+0192 glyph is qualified as small letter /f with hook and as florin. But the first is a normal roman glyph, the second should be all italic. In fact in various fonts the rendering is different, in some precisely a /f roman with hook, in others all italic. What is the correct rendering in roman/regular?
2) Does it make sense to produce the small cap version of glyphs like U+0221, U+0235 and U+1EFF, i.e. /d and /t with hook and /y with loop?
