Ravi,

First off, this would probably be a better question for a Javascript  
mailing list as this isn’t really a rails-specific question.

In an effort to help you out, you’ll probably want to look at building  
an observer with javascript (using prototype.js) and validate that  
characters are non-numeric. I’m not sure how TinyMCE works completely,  
but it sounds like it’ll generate the html as you’re using it but I’d  
suspect that it’d key a variable in it’s namespace with the original  
content so that it could continue to reformat properly. Perhaps it’s  
has an html escape function that you could call to strip out the html.

Anyhow, that’s how I’d go about looking to create a solution to your  
goal.

Cheers,  
Robby
