Well I made some tests with a text without spaces and there are
always differences:

 Arial XeTex 179.57892pt luatex 179.57878pt.
 Latin       176.98479pt        177.29143pt.

To complicate things some fonts exists in more than one version on
my PC (e.g. in windows/fonts and in the texmf-tree), so one should
check carefully that the same fonts are compared.
