Sacrebleu

I created a demo so show you how easy this is. The screenshots below show before and after entering Portuguese text with diacriticals into a multi-line text field:

Notes:

(1) Funny:  To get the demo to work I changed the event from "input" to "blur" because every time I pasted Portuguese into the <textarea> the script immediately fired the input event and removed the diacriticals without ever seeing the Portuguese. So I changed the event to blur to slow down the conversion process and grab a screenshot.
