IMO "c4" case (c4: String1250 = 'áéíóčž';) is not fully explained. 
Probably what here happens is, that declared code page of c4 = source 
file code page and in that case compiler does not insert conversion 
code. StringCodePage(c4)=1250 (also StringCodePage(c2)=1250) so dynamic 
code page is right, but when assigning to TLabel.Caption current dynamic 
code page is not taken into account

yes I use this, but I have "one" specific case where I want share one 
file between Delphi7 and Lazarus

Yes this is what I use (WideString constants) and it is only solution 
which works for me in Delphi7/Lazarus

Thanks
