I'm not a peep...
Perhaps you have bleed and document information turned on when making the pdf? That will embed a version of Arial in the pdf. I don't think, if this is the case, that using the convert fonts to shapes, or outlines, during making the pdf will overcome this, but it may. I'm not at a computer to check.
Beyond that, I would need to see the pdf or the Xara file.
