Perhaps you need to look for a 3rd party app to find the accents you require......many, many keyboards/styles on the Google Play Store
Hi @hugoxrosa,
As posted by @dandy63 above, I would recommend that you try to see if there is a Keyboard suitable for you available in the Google Play Store.
I'm afraid I just had a look in the Xperia Keyboard with the latest available update and there is currently no support for the special characters you listed, alternate layouts or auto correction while not automatically capitalizing letters.
