Forum: Ruby on Rails html escapes on conversion/migration from rails 2 to rails 3

I am converting/migrating an app from rails 2 to rails 3.  Along with 
other
things that must be changed, I am encountering scattered instances of
string literals and strings returned by helpers in templates that are 
being
automatically html escaped on rails 3.  Are there any tools or 
techniques
to identify and perhaps automatically correct these instances or is
continuing to find them piecemeal the only way to proceed?  Thanks
