Question: Symbolic characters in plot titles?

Hello, I am relatively new to Maple and using version 9.5. Does anyone out there know of a way for symbolic characters such as Pi to appear in a plot title? This is the input I am working with. f:=x->piecewise(x < Pi/3,4*sin(x),Pi/3 <= x,x^3-x+1); plot (f(x),x=-Pi..Pi,discont=true,title="f(x) [-Pi, Pi]",titlefont=[TIMES,BOLD,16]); Any help would be greatly appreciated. Thanks
