String to Enum With Empty String Error

[Hooovahh]

I have what I think is a bug, but you could also argue this isn't a great design. I have an enum that has the first value an empty value.  If I convert that to a string, it returns an empty string.  So far so good.  But if you then use the Scan From String to turn it back into an enum, it generates an error. I have a VIM for doing XML reading and conversion to a data type and this is generating an error.  Attached is a VI showing the behavior.  Is this the expected behavior? Is there a better work around?  At the moment if the string is empty, I have it then look for for each of the string values for each of the enum values and seeing if one is empty.

Does it have to be an empty string?

Can you use character 127?  It looks blank.

Here it is with the 1st element as chr 127.
