IsValidChar is a Boolean function that indicates if the Field specified in AField contains the UTF-8 encoded character in AChar. No action is required (or performed) when AChar contains a single byte character.
Please note that TField does not contain a method which verifies a Unicode character. This routine converts a multibyte Unicode character using UTF8ToSys and calls the TField.IsValidChar method to validate.
IsValidChar returns True when TField.IsValidChar returns the same or when AChar contains the BackSace (Decimal 8) character.
