Hi Rohen and jkid20 - what you've hit upon there is that Google 'normalises' accents that have an impact on meaning and ignores those that don't. This is a very general rule and I have seen the normalisation turned off and back-on.

However, I'm not sure that that means Spanish qualifies as a difficult language to optimise for? Surely that means Spanish is easy as there are relatively few accents and Google is correcting anyway? Now as for French with it's 5 or 6 accents? Or Russian with its word declensions..... I have to say I'd rate Spanish one of the EASIER language to work with
