BDS 2006 All SP/HotFixes applied:

Can someone explain this to me please?


AnsiString s1 = "Test";
int len1 = s1.Length();  // len1 = 4
TVariant v1 = s1;
Variant v2 = v1;
AnsiString s2 = (AnsiString)v2;
int len2 = s2.Length(); // len2 = 5 ?!?!?!?


Am I missing something, or did BDS just try to pull a fast one on me?

Replaceing

AnsiString s2 = (AnsiString)v2;

with

WideString s2 = (WideString)v2;

produces the correct results (i.e. length is 4...)

There appears to be a problem converting a Variant of type VOleStr to an 
AnsiString.  Can anyone confirm this for me?
