“Someone incapable of properly reading a food package, whether due to time, reading, language, or other limitations should not be making purchasing decisions.”
So if you are stranded in France because of engine trouble and need to buy some food to tide you over Shabbos, you will choose to fast over Shabbos if you can’t read French? Sounds pretty simple minded to me.
I suggest in this case you simply try to find a local heimish hechsher on the packaging and leave the OU on the shelf, in case the whole package isn’t kosher.
