ReNamer:Scripts:Convert file content from ANSI to UTF-8

Convert the content of processed files from ANSI (default system code page) to UTF-8 encoding.

To prevent files from being processed more than once, we will insert the UTF-8 byte order mark (BOM) "0xEF 0xBB 0xBF" at the beginning of converted files and check for it before processing the file.

var
  DataAnsi, DataUTF8, UTF8BOM: AnsiString;
  DataWide: WideString;
begin
  UTF8BOM := Chr($EF) + Chr($BB) + Chr($BF);
  DataAnsi := FileReadContent(FilePath);
  if Copy(DataAnsi, 1, Length(UTF8BOM)) <> UTF8BOM then
  begin  
    DataWide := AnsiToWide(DataAnsi);
    DataUTF8 := UTF8BOM + UTF8Encode(DataWide);
    FileWriteContent(FilePath, DataUTF8);
  end;
end.
