IE vs. Firefox - SPACE character

I am seeing a difference in the way FF encodes a blank space vs. IE.

For some reason, when updating a cell in a grid (rule or test scenario), FF is passing down spaces encoded as FFA0 (FFA0 hex == “HALFWIDTH HANGUL FILLER”). With IE, it is encoded as 32.

This is causing issues in my application (one guy uses FF to update something, another guy uses IE to validate the contents, and the compares are failing).

How can I get FF or IE to treat spaces the same way? Or do i have to convert each string on the server side to normalize the space characters?

Unfortunately you will have to convert the data on the server-side.
