The same way you would for a normal PChar to a long string, mostly.
SetLength your Delphi WideString variable to the required length, and
Move() bytes from [the first character in] the source to [the first
character in] the destination. Watch out for strings SetLength'ed to
zero.
TStrings contains ANSI strings, not wide strings. Characters not present
in your active codepage will become question marks in conversion.
