The default encoding for recent versions of TeXShop has changed from MacOSRoman to IsoLatin9. Do you have a line like

% !TEX encoding = xxxx

where xxxx is the encoding used for the file?

Is there a reason you have the default set to UTF-16 rather than UTF-8? In any case, are you using xe(la)tex or lua(la)tex to compile your files? If you're using pdflatex do you have a line containing \usepackage[....]{inputenc} where .... is the encoding used for the file?

Good Luck,
