Anchor text and  

Assuming that google considers anchor texts to evaluate your page/site
subject/keys, can "backspace characters" cause problems?
I mean if I put a tag like this:

<a class="servizi" href="" title="">Certificazione &nbsp;&nbsp;e
Sicurezza</a>

does google consider it identical to:

<a class="servizi" href="" title="">Certificazione e Sicurezza</a>

and then give to the linked pages the same score for the key "certificazione
e sicurezza"?

Thanks,
Alessandro
