French headsets were also a little different and finding french stems is apparently an even bigger pain in the ass. Fortunately, you can take a regular stem and basically sand off a very small amount and make any stem fit. This is only what I have been told or read and I have not tried it. For some reason, my Peugeot had a fork and headset that accepted standard quill stems.

You could also just replace the fork and headset to eliminate that problem.
