But what does your program prove ?
See below...
You're only proving that a conversion happens when you do
s := fieldByName('somefield').asString;
I'm proving that using the String type anywhere in the RTL and FCL is
now terrible. If the FPC team did a search and replace (String ->
UnicodeString) all over the RTL and FCL, then such data corrupts
probably would not have occurred because UnicodeString is not affected
by the running environment. Probably the exact reason why Delphi now
using String = UnicodeString on all platforms.
It would not help if we did this: the data would be wrong in the TDataset
buffers, and the result would be worse.
I agree that the situation is currently not ideal: TString.AsString is a
problem, but it's not nowhere near as bad as you make it out to be.
You just need to know what conversions happen where, and if you do it
works just fine.
Michael.
