I understand "By default, variables declared as type String are 
*UnicodeString*.**", that String=UnicodeString
 See: http://docwiki.embarcadero.com/VCL/en/System.UnicodeString
 and also 

Note alse, that AnsiString holds additional informations about character 
 "The AnsiString 
<http://docwiki.embarcadero.com/VCL/en/System.AnsiString> structure 
contains a 32-bit length indicator, a 32-bit reference count, a 16-bit 
data length indicating the number of bytes per character, and a 16-bit 
code page."
