Thank you very much.
Now it's working quite fine.
Anyway I'm trying to write equations in bold and italic style.
If I use \mathsymbol or the package bf with the command \bf they doesn't make my symbol bold (while they still are italic).
Does anyone know how to do it?

Hi everybody,

I need to use the raleway font to write a document.
Particularly I'd like to write equations too in this font.
Is it possible? How can I do?
