Translate more French strings and escape the non-ASCII chars.

I've translated more French strings.  I've escaped the non-ASCII chars using the following command (hopefully that includes all the chars used in the French translation):

ls *.js | xargs sed -i 's/\à/\\u00E0/g'; \
ls *.js | xargs sed -i 's/\ç/\\u00E7/g'; \
ls *.js | xargs sed -i 's/\è/\\u00E8/g'; \
ls *.js | xargs sed -i 's/\é/\\u00E9/g'; \
ls *.js | xargs sed -i 's/\ê/\\u00EA/g'; \
ls *.js | xargs sed -i 's/\ë/\\u00EB/g'; \
