French characters on a chinese machine

Hello.
We have an application that teaches French.

Running on Chinese windows, anytime a French character comes up on the screen such as è or ê (all valid ASCII characters), chinese characters come up in their place.


So instead of seeing "frère", the person sees "fr[chinese character]e" where [chinese character] would of course be a Chinese character which I can't draw here.

Any ideas how to solve this?

After all, if I say label.caption="frère" and all the characters are in the ASCII set, then it would be expected that the word "frère" appears on the screen.

Any help would be appreciated.
