Latex Commands in Titel get mangled

Hello,

trying to edit an entry in my bibtex file with a Chemical Equation in the title (H20). I wanted to use \ce{H20} to do that (works with plain files) but if I edit the file with kbibtex, \ce becomes ȩ which is a dangerous silent error. You end up with an incorrect bibliografy without even a warning.

Is there something we can do about that? Cheers
