Add the line \usepackage[T1]{fontenc} to your preamble to use the  CMSuper fonts or ALSO add the line \usepackage{lmodern} to use the Latin Modern fonts.

I am not an expert on encoding, but I think the problem is more fundamental. For one, I use LuaLaTeX where fontenc et al. do not apply. On the other hand, I see this basically with every PDF, not matter where and how they were produced. This is definitely a problem of PDFKit. If I copy a german text from a PDF ä, ö and ü are copied incorrectly. They are displayed correctly, but they seem to be combined characters, as you say, but this is not LaTeX related (a typical scenario: I copy text from a PDF to TeXShop. An umlaut like „ä“ looks correct in the source, but when I typeset it, it is displayed as „a“ since it obviously wasn’t copied as a proper „ä“). Fl and fi ligatures aren’t copied at all, they just result in empty space. Acrobat on the other hand, handles both elements flawlessly.
