Hi,

In windows legacy, it seems double quote is normalized and any double quote characer is accepted. However, at this time, in windows (.net6) ,in fact, only `"` (0x22) is accepted to express string literal. To make matter worse, it seems to occur only compiling. (Expression validator don’t raise an alert.)

FYI, the following is sample for reproducing. The first Assign uses `"` 0x22 and second Assign uses `“` and it fails in compiling.
