advanced word course in london - Word Encoding Problem

Hi,

I am sorry if I am posting this question in a wrong forum but I have a serious problem with a Microsoft Word Document. I have recovered so many of my important .,doc files from my formatted HD. Some of them are readable while others are not readable as they appear on some other format. There is a warning that " Select the encoding that makes your document readable." I am also uploading the screenshot of my problem.

Please help me in solving this problem as those documents are very important.

Thank you
