How to convert UnsafePointer<CUnsignedChar> to String?

Question

I have tried this method:

String.stringWithCString(cString: UnsafePointer<CChar>, encoding: NSStringEncoding)

But unfortunately, it only work with UnsafePointer<CChar>. And I have no idea about how to convert UnsafePointer<CUnsignedChar> to UnsafePointer<CChar>.

Since Swift 3.0

let str = String(cString: UnsafePointer<CChar>(ptr))
