Absolute position of character in textarea

Is it possible to get absolute开发者_高级运维 position of character in a textarea?

Yes, but it's much more complicated than it should be.

There is a demo demonstrating exactly this functionality, and the method used is discussed in this related question.

Theoretically yes, it is possible, you need to simulate browser's text rendering! But that would be so complicated that I would never even start thinking about it :)
