Hi David and thanx.

I must correct myself. Acutally it's not the 2 tokens synonym to create the error but the diacritic.

the original row was:

abbattere, ammainare, peggiorare, tirare giù =\> this causes the malformed error because of the ù

If ireplace ù with u' it works!

abbattere, ammainare, peggiorare, tirare giu' =\> OK

Therefore i think i'm going to replace all the diacritics

Thanx valerio
