There is some redundancy in UTF-8 format so you can test if your string is a valid UTF-8 string. There is std.utf.validate() for you. Any ASCII string will also pass since ASCII is a special case of UTF-8. Not all code points are defined in Unicode. This means you can cast your string to wchar[] and then test every char using the std.utf.isValidDchar() function. If it fails, then you definitely not dealing with a valid wchar[] string, so test dchar[] similarly. Be prepared though that these tests will sometimes give you false positives.
