Regex Tester & Validator

Matches one or more characters consisting of English letters (a-z, A-Z), Spanish accented vowels (áéíóúÁÉÍÓÚ), ñ/Ñ, spaces, and special symbols (@, &, ., _, $, -). Typically used in Spanish-language form validation for fields like names, business names, or addresses where letters are expected but limited punctuation is tolerated. Note that despite the 'only letters' intent, the pattern also accepts spaces and several special characters, so it is more permissive than a strict alphabetic check.
