Symbol Hound - The search for devs.

During the course of the last week myself and a college came across an exception in our logs. The exception was from JSON.Net complaining of an unexpected character in the JSON string.  The character in question was the ^@ symbol.  A Google search for this symbol shows up very unhelpful results, you could try Carrot @ or Carrot At.

We went looking for ways to search for symbols in Google, in our searches we came across http://symbolhound.com a search engine for developers. It doesn't ignore symbols so a search for ^@ yields much more useful results and reveals that its a null character. It's a useful tool for debugging and development questions, you can even set it as one of the search options in Firefox.
