how to clean a string from non-html sequences ?

using the CKEditor to enter post content, I get a string as output ,
with some escape sequences \r\n\t ...
is there anyway to clean it before saving the post record to the db?
any kind of html.clean method like the html_safe , or should I
perform a gsub ?

thanks for feedback

Can CKEditor clean escape sequences?

I'll check ... at least I can gsub the output ...
thanks

Probably the best way is to use before_save block in model where u can
add

attribute_with_html.strip

thanks .. done
