HTML Character Encoding

OK, well we only need to allow this for one script which passess data from an SMS company to my company. The data (filename, text message, date, and some other parameters) is then put into a database, and the image/video texted in is then copied accross from their servers to ours. So I don't think that this would cause too many problems, especially if I had a password as one of the parameters, which would add a layer of securtity.

Is it possible to bypass the permitted character check, just for one controller/function?

If not, my solutions would be:

1) Use traditional query strings, but I guess if I use it for this I need to use throughout the application, which is not ideal.

2) Use another method of encoding which would work both ends.

The characters in the parameters could be anything in a text message, which includes all common symbols.

Any thought on how this could be resolved, I would be grateful.
