Regex Editor & Tester

Matches any single character that falls outside a whitelist of safe text characters: letters, digits, Italian accented vowels (à è é ì ò ù), the euro symbol, common punctuation, and whitespace. With the 'i' and 'u' flags enabled, it accounts for both letter cases and unicode handling. Typically used in input validation or sanitization to flag unsafe or unwanted characters, especially in Italian-language text fields.
