Will maple show Plank's constant "hbar" as one letter not three letters in 2D output?

> restart;

dotpro := (psi,phi,L)->int(evalc(conjugate(psi)*phi),x=-L..L);

dotpro(exp(I/hbar*p*x)/sqrt(2*L), exp(I/hbar*q*x)/sqrt(2*L),L);

Google Desktop search has already been widly used, so why not develop a plug-in for maple document and helpfiles?
