Great find. We also started to manually work on lang translations for D7 a few weeks ago, and were a bit concerned about apostrophe's as well. Since our first lang translation was into Spanish, however, all accents and "ñ" letters were parsed perfectly.
So, when you mention the need to "tale precautions", the fix is to escape apostrophe's using the "/", right?
