[Tutor] putting accent on letters while user is typing in Entrybox (Tkinter)

[Ali M]

The accents which i want to be automatically converted and put upon letters
is circumflex and another one which shape is like the opposite of
circumflex.

the user types in entrybox and it searches in db which i've created before
and has no problem. the words in my db have unicode characters and they are
accented. the user himself can type accented characters too, but i want to
make it automatically converted so the user doesn't have to have a special
keyboard to write.

when x is pressed after these letters (g,j,c,h,u), i want that x to be
removed and replaced with a circumflex above those letters.

here is the full code if needed:
