Thanks I've added your encoder and bugfix. Although a generic regular 
expression encoder would be better, it would probably take too much 
effort at this point to get it done and this strip encoder meets a 
common request and is a lot faster than using an external tool such as 
sed with the command encoder.

I don't know about wxspencer on Windows, someone would need to find the 
time to debug it. You are probably the first to test it on Windows.
