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.

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.

Open in TeXShop (or with UTF-8 encoding in another editor) or via the Terminal (using pdflatex). You should be able to Copy/Paste ok. Well, the spaces between the characters is lost probably because (pdf/xe)(la)tex doesn't really use space characters but glue.

Then comment out the \usepackage[T1]{fontenc} line and try it again. This time there is a problem.

Good Luck,
