This is an archived snapshot of W3C's public bugzilla bug tracker, decommissioned in April 2019. Please see the home page for more details.
Internet Explorer, Firefox, and Opera all support the textLength DOM attribute on <textarea>. Sites rely on it as well as far as I know. Newlines are counted differently in browsers. Have not checked whether it counts 16-bit units, actual characters, etc. Also not sure whether any of these details matter, but long term it would be good if they were clear.
