MAN OF LA MANCHA was translated into French in 1965 by Jacques Brel, who also starred in the production opposite (yep!) Joan Diener.

You can find the original French cast recording on Amazon.com. I don't know what the lyrics to "Aldonza" are in French, but you can listen to a snippet.

As has been discussed above, there are several variants in English.
