A complete minimal example of LaTeX document may describe better what are you trying to achieve. I believed that a usual issue is to allow unicode characters typed using compose key: α → ∞. LuaLaTeX should work with Unicode better than PdfLaTeX, however fonts must be explicitly configured. Fortunately it is easier to use e.g. truetype fonts.
