AFAIK, in current Delphi (which I don't have) a "String" is a variable
that can contain dynamically coded informations (such as locally
coded 8-Bit ANSI, UTF-8, UTF-16, ...) and - of course - know which
code it holds.
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
http://docwiki.embarcadero.com/RADStudio/en/String_Types#UnicodeString
Note alse, that AnsiString holds additional informations about character
encoding:
"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."
-Laco.
If a string is generated by the VCL from a Window API function, the
coding will be UTF-16, though, but if you create a string with some
other coding it will be automatically re-coded to UTF16 before sending
it into a Windows API function.
