Because I can load ä.tex with `tex-main-file' replaced with `TeX-master'
with AUCTeX enabled:

--8<---------------cut here---------------start------------->8---
\documentclass{article}

\begin{document}

master-foo

\end{document}

%%% Local Variables:
%%% coding: utf-8
%%% mode: latex
%%% TeX-master: t
%%% End:
--8<---------------cut here---------------end--------------->8---

and can compile it successfully by hitting C-c C-c.

I'm not familiar enough with the internals of tex-mode.el and what
happens after hitting "C-c C-c RET", but after having another look, I
think that the current invokation:

  pdflatex  \\nonstopmode\\input \ä.tex

should be:

  pdflatex  \\nonstopmode\\input \\detokenize{ä}.tex

I agree, the issue isn't related to codeset etc., AFAICT.
