Diacritic (¨/ ^ / é / ù ...) and failling researches

Hi,

I've experience missed record following a research with a word which includes diacritic. I.e searching for Opera doesn't give records with Opéra. Lazy frenches! but honestly, it can some orthographe can be tricky. Others softwares don't give importance to diacritic either it's typed or not, but Ninox does.

Is there a way to avoid this, please ?

Looking forward to hear from you,

Regards,
