The Sorokin one. I've been using it for years for ASCII, but it has an 
internal flag to use widestring:

// ======== Define options for TRegExpr engine
{.$DEFINE UniCode} // Unicode support
..
type
  {$IFDEF UniCode}
  PRegExprChar = PWideChar;
  RegExprString = WideString;
  REChar = WideChar;
  {$ELSE}
  PRegExprChar = PChar;
  RegExprString = AnsiString; //###0.952 was string
  REChar = Char;
  {$ENDIF}

It almost works: Exec() is OK (at least with trunk, I might have seen a 
problem with a version a few weeks old) but Match[] isn't.
