CheckUTF8MBS(data as ptr, size as Integer, Placeholder as string) as string

This function is more save than simply DefineEncoding as it makes sure the returned text actually is valid UTF-8.
You can replace missing characters with empty text, question mark or any other symbol.

This function is overloaded, so you can directly pass in string, memoryblock or ptr+size.
Checks byte sequence with up to 4 byte long sequences. Does not verify whether code points are valid.
