With Symbol from my windows install I got the same problem.
Like I say in http://bugs.freedesktop.org/show_bug.cgi?id=26139 , If I replace /usr/share/fonts/X11/Type1/Symbol.pfb with symbol.ttf I could see everything ok in the document, Pi character,etc., but that messes up openoffice.
(About OO, I can't reproduce it know but it has done things weird in the past exporting to pdf after changing that font)
