> There is a problem with the length of text with line breaks.
> The [HTML5|https://dev.w3.org/html5/spec-preview/the-textarea-element.html] spec. says, CRLF has to be treated as a single character in the browser .
> Over HTTP/1.1 two characters must be transported.
> When the string is validated in a JSF <f:validateLength> the String is N characters longer than in the browser, when it contains N line breaks.
> To "repair" this situation, Tobago should replace CRLF with LF in the submitted values of textarea.
> For compatibility reasons, this should be configurable in the tobago-config.xml: 
> {code}
> <!-- true is the default -->
> <decode-line-feed>true</decode-line-feed>
> {code}
