Regarding the second remark, it turns out I was wrong. I don't  
understand fully what happened, but it seems to be connected with  
TeXShop no longer recognizing by default the older syntax:

     %&program=xelatex
     %&encoding=UTF-8 Unicode

I took a former XeLaTeX file of mine, in UTF-8 encoding and using  
that syntax, and opened it in TeXShop, with MacOS Roman encoding as  
the default (for these occasions when I'm not using XeTeX). Then I  
replaced the above two lines by the new syntax:

     %!TEX TS-program = xelatex
     %!TEX encoding = UTF-8 Unicode

and saved then typeset the file. However, because the modification  
had taken place in a TeXShop not recognizing the former syntax, the  
file has not been recognized as UTF-8 endoded upon opening, but as  
MacOS Roman encoded, and finally not saved in the proper (UTF-8)  
encoding.

When opened afterwards, because of the correct new syntax, the file  
was identified as UTF-8 encoded, which its wasn't; hence the improper  
XeLaTeX output, with esoteric (square root etc.) symbols where  
accented letters should have been. If, on the other hand, the second  
line "UTF-8 Unicode" was replaced by "UTF-8Unicode", as I did later,  
then the file was not interpreted as UTF-8 input and yielded (oddly  
enough) correct XeLaTeX output.

Two more things I tried:

- Taking the original file and modifying it this time in TextEdit  
which is (in its default settings) encoding-agnostic. Then opening  
the file in TeXShop and XeLaTeXing it yields correct output.

- Using the instructions at <http://www.uoregon.edu/~koch/texshop/ 
changes.html> to get TeXShop recognize the former syntax in addition  
to the new one:

     defaults write TeXShop UseOldHeadingCommands YES

Then the file can be modified and compiled in TeXShop, yielding  
correct output.

In summary I think that, for the sake of compatibility, it would be  
nicer to have the former syntax recognized by TeXShop in addition to  
the new syntax.
