copied!<p>Here is the complete code that solved my problem:</p> <pre> function Unescape(const s: AnsiString): string; var i: Integer; j: Integer; c: Integer; begin // Make result at least large enough. This prevents too many reallocs SetLength(Result, Length(s)); i := 1; j := 1; while i <= Length(s) do begin if s[i] = '\' then begin if i < Length(s) then begin // escaped backslash? if s[i + 1] = '\' then begin Result[j] := '\'; inc(i, 2); end // convert hex number to WideChar else if (s[i + 1] = 'u') and (i + 1 + 4 <= Length(s)) and TryStrToInt('$' + string(Copy(s, i + 2, 4)), c) then begin inc(i, 6); Result[j] := WideChar(c); end else begin raise Exception.CreateFmt('Invalid code at position %d', [i]); end; end else begin raise Exception.Create('Unexpected end of string'); end; end else begin Result[j] := WideChar(s[i]); inc(i); end; inc(j); end; // Trim result in case we reserved too much space SetLength(Result, j - 1); end; const NormalizationC = 1; function NormalizeString(NormForm: Integer; lpSrcString: LPCWSTR; cwSrcLength: Integer; lpDstString: LPWSTR; cwDstLength: Integer): Integer; stdcall; external 'Normaliz.dll'; function Normalize(const s: string): string; var newLength: integer; begin // in NormalizationC mode the result string won't grow longer than the input string SetLength(Result, Length(s)); newLength := NormalizeString(NormalizationC, PChar(s), Length(s), PChar(Result), Length(Result)); SetLength(Result, newLength); end; function UnescapeAndNormalize(const s: AnsiString): string; begin Result := Normalize(Unescape(s)); end; </pre> <p>Thank you all! I am sure that my first experience with StackOverflow won't be my last one :-) </p>
