Non-Latin Characters in URLs

[Norman]

For example, is this okay for SEO?
site.com/3338-test-nuova-è-okay-adesso-proverò.html
Or should I replace them?

The best I could find from Google was this:

If you want to create URLs with non-English characters, make sure to use UTF-8 encoding. UTF-8 encoded URLs should be properly escaped when linked from within your content. Should you need to escape your URLs manually, you can easily find an online URL encoder that will do this for you. For example, if I wanted to translate the following URL from English to French,

http://example.ca/fr/mountain-bikes.html

It might look something like this:

http://example.ca/fr/vélo-de-montagne.html

Since this URL contains one non-English character (é), this is what it would look like properly escaped for use in a link on your pages:

http://example.ca/fr/vélo-de-montagne

A more recent article - although not from Google, so less authoritative:

Do either of those help?

A common practice is to have “slugs” where page titles are transliterated into their <128 byte equivalents or sometimes something slightly different. eg the slug might be

test-nuova-e-okay-adesso-provero
but the page title would be
Test Nnuova é Okay Adesso Proverò

Thank you guys. Basically now I have this URL: test-nuova-e-okay-adesso-provero.html, with the page title as “Test Nuova è Okay Adesso Proverò”.
So I’ll probably stay with that, just to be sure. I was asking this just to know if there would be some benefits on using them or not, even on SEO (excluding the visual benefit).

Edit, in the second article the advice is to use them… umhhh. The main issue seems to be with old browsers.
