Deleting special characters except spelling accents

Issue

I would like to create a regex to help me to delete only special characters except spelling accents. For example:

João Maria-JOSÉ!!!

I would like to print

João Maria JOSÉ

Heeeelp?

Solution

Use UNICODE_CHARACTER_CLASS
(?U)
together with the negation of the Alpha character class
\P{Alpha}

Example:
"João Maria-JOSÉ coração!!!".replaceAll("(?U)\\P{Alpha}", " ")

resulting in
"João Maria JOSÉ coração "
