Turing can only display fonts that are installed on the system running the program. If Wingdings is installed, there may be another reason it fails to load. Fortunately, the Turing documentation gives us a method to determine the cause of the failure:
If the Font.New call fails, then it returns 0. Also Error.Last will return a non-zero value indicating the reason for the failure. Error.LastMsg will return a string which contains the textual version of the error.
