Because my picklist displayed special characters not corretly I changed all itens for non special characters

Now, same filters not dipslayed correctly a value for this

Example "Cartão de Crédito"  was changed to "Cartao de Credito"  but filter not listed any more

Same if  I change the same way in filter condition

How I can solved that?

You shouldn't have changed the picklist values, you should have fixed the problem with your install.

You will have to go to the translation module and update the picklist translation records with the same change you made in the picklist.

When I returned a old value in my picklist, filter works again

I only renamed the item to "Audiência" , with accent again ...
