The LEFT$ returns the specified number of characters from the left-hand side of the string.
In UTF-8 supporting versions 4.5.1 and higher NULL characters are no longer cut
out from strings, resulting in a different behavior:
Len of Chr$(0) is 1:
In former versions NULL characters could not appear in the middle of strings,
since theconcationation process cut these characters from the resulting string.
