Ways to detect that XXXX in JSON \uXXXX does not correspond to a Unicode character?

Hi Folks,

The JSON specification says that a character may be escaped using this notation: \uXXXX (XXXX are four hex digits)

However, not every four hex digits corresponds to a Unicode character.

Are there tools to scan a JSON document to detect the presence of \uXXXX, where XXXX does not correspond to any Unicode character?
