Problem with permalink special char

Hi,

I have built a website including lots of items (projects)
giving them a title like “Art. 01 · Name…”

Unfortunately, the “·” char is also in the permalink,
so that when I copy the url, I cannot share it,
as it is like this: https://komplast.it/project/art-998-%c2%b7-profilo-54×54/
with “%c2%b7” that replace the char “·”

How can I do to replace all the special characters with normal characters?
Is there a way to do it globally?

One by one would be a long job, as I have lots of items to edit,
in Italian and also in English language…

Thanks
