Recognizing unicode is possible, recognising 8 bit encodings is not
possible, not reliable anyway. For TeX itself you use
\usepackage[utf8]{inputenc}, and it would be good if TeXShop recognizes
this.

There are several other settings that can be specified with %! like the
default command to process the file, the file which contains the
\documentclass - or at least where processing should start.

TeX itself knows nothing about Cocoa, so for TeX you need another method.
However, as far as TeX is concerned the %! commands are just comments, and
won't be used by TeX. It is just TeXShop which uses them.
