Bug with smart quotes in a string

@KathleenDollard , @AnthonyDGreen
We just found a bug in VB.Net.

VB supports smart quotes around a string, so the following is a valid statement
Dim x = "bla bla “” bla bal" 'All smart quotes - this compiles.

But it returns:
bla bla " bla bal
The quote returned is a NORMAL - NON SMART quote.

This causes a problem where smart quotes can not be used in strings.

A proper way to handle this is that it would add the second quote to the string, as the first one is the escaper of the used quote.
