I know this too well. Some pages will tell me that my name or address is &#x27;invalid&#x27; because it contains spaces or forbidden characters.<p>I&#x27;m sorry, but &#x27;ñ&#x27;, apostrophes and accent marks are not forbidden, and no name should be ever &#x27;invalid&#x27;. How can a name even be &#x27;invalid&#x27;? Sometimes I think too many sites assume (wrongly) that all customers will be an average english-speaking, US-resident person.
