Hi,

I’m using the Builder gem to transform an array/hash that contains  
serialized ruby. Builder’s to\_xs method seems to mangle serialized  
ruby though. I can get around this by encoding/decoding with base 64,  
but that doesn’t seem like a good path to follow.

Builder is using this code for escaping:  
[http://intertwingly.net/stories/2005/09/28/xchar.rb](http://intertwingly.net/stories/2005/09/28/xchar.rb)

Any ideas on how to modify that, so serialized ruby will be escaped  
properly?

Thanks,  
Matt
