Howdy,

By the way in TeXShop 3.59 and later there is a new Help document that is a Beginner's Guide to File Encoding.

I'll be your templates are NOT saved as UTF-16. I'd try to open them with UTF-8 (if they are traditional ASCII the UTF-8 setting will still be OK while I don't believe ASCII is a sub-set of UTF-16 since every character is 16 bits in that file version of Unicode.

DON'T simply try to change the file and save it. That can destroy the the contents of the file.

Also... ALL templates should have a 

% !TEX encoding = XXXXX

directive to tell TeXShop what encoding to use to open the file. It should also have a

\usepackage[xxxx]{inputenc}

line to tell latex or pdflatex what encoding is being used. If you are using xelatex or lualatex you should be using UTF-8 Unicode encoding by default or have some commands that tell those engines what encoding you are using.

PS: if your templates have accented characters you are are not using ASCII and you really NEED to have the information above. For German you usually use IsoLatin (latin1) or IsoLatin9 (latin9) but there are lots of possibilities.

Good Luck,
