Handling Non-UTF-8 Params In Rails
Today I woke up to the following 500 error notification from mindfulchoices:

What can you do if/when a client refuses to conform and sends non-unicode characters to your server? Surprisingly, I couldn’t find an idiomatic solution to this issue.
Since my code was already using Rails Strong Params, I bolted some extra code to the end of the method, stripping out any non-UTF-8 characters:
I’m curious, do you know of a better (more “Rails-y”) way to mitigate this problem?
