Displaying Accented Characters in Chinese Windows

Hi,

We wrote a program that is localized into different languages
including Simplified Chinese, Spanish and French. When our installer
runs, it would ask the users to choose the lanugage to install the
software in, including Spanish (Español) and French (Français). The
problem is the character ñ and ç becomes Chinese characters when the
installer is running in a Chinese Windows, since the chinese character
map is different.

I was wondering if there is any way around this.

P.S. Can the character ñ and ç even able to display correctly on a
Chinese Windows? I tried looking through the Chinese character map, I
don't seem to be able to find those two characters.

Any help would be greatly appreaicated

Thanks,
Peter
