Thanks Craig.

I checked again. I think the Belgian result is as expected. In http://msdn.microsoft.com/en-us/library/kf2c7kaz(v=vs.80).aspx it says that "To match the length of the longer expression, the shorter of the two expressions is padded to the right with spaces or zero (0) bytes. However, any trailing spaces or zero bytes in the expressions are disregarded in the comparison.", which should make " " and "" equal. So why doesn't tht work in Shanghai? My money is on keyboard drivers.

Anyway, you're right. I'd better change the code, but was hoping to find the reason, because god knows how much times we used this blasphematory construction :)
