In `Text.php`, `buildControlCharacters()` constructs array of control characters, but only characters 0 - 19(without 9, 10, 13). If i create Word2007 file with some other control character, for example 20, generated file is corrupted. Sample: ```php $phpWord = new \PhpOffice\PhpWord\PhpWord(); $section = $phpWord->addSection(); $section->addText('control char 27(ESC):' . chr(27)); $objWriter = \PhpOffice\PhpWord\IOFactory::createWriter($phpWord, 'Word2007'); $objWriter->save('test.docx'); ```
