How to extract cell comments in phpexcel?

Question

PHP

Good afternoon.
I need to pull out a comment (note) from a cell, I do it as follows:

echo (string)$worksheet->getCommentByColumnAndRow($row, $col)->GetText();

But instead of the text:
фывфффффффы sadssssasd 231 #$#%*(&@
I get the text:
DK2DDDDDDDK sadsss
It turns out that Russian letters are encoded as English, and some are cut off altogether.
As far as I know this Excel file was made by 1C.
How to pull out a comment with Russian words?
Solution:
Convert file from xls to xlsx

Answer 1

It was decided by resaving the document from xls to xlsx.
XLS does not support comments even if they are saved and displayed in MsExcel 2007+
Converting from xls to xlsx:

$objPHPExcel = PHPExcel_IOFactory::load("XMLTest.xml");
$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel2007');
$objWriter->save('covertedXml2Xlsx.xlsx');

But now the comments turn from: to
:

9_x0004_F_x0004_C_x0004_:_x0004_5_x0004_=_x0004_3_x0004_H_x0004_I_x0004_7_x0004_E_x0004_J_x0004_D_x0004_K_x0004_2_x0004_0_x0004_

В браузере отображается как:
9FC:5=3HI7EJDK20
И при копировании в блокнот++ между каждой буквой юникодный символ "EOT"

And many characters are cut off.
If you convert MsExcel, then everything is fine, even long comments.
