Breton Characters U+A742 and U+A743

Hello,

These characters are used in the breton language (brezhoneg) and stand for the word, usually used as a prefix, "Ker" (or "ker").

Is there any way to specify this expansion in a setting of a font so that a search on "ker" world return ꝃ and vice versa?

Thank you for your help,


p.b.
