How to detect if a string is encoded with escape() or encodeURIComponent()

Question

I have a web service that receives data from various clients. Some of them sends the data encoded using escape(), while the others instead use encodeURIComponent(). Is there

You don't have to differentiate them. escape() is so called percent encoding, it only differs from URI encoding in how certain chars encodes. For example, Space is encoded as %20 with escape but + with URI encoding. Once decoded, you always get the same value.
