An Excel file opens in Studio with corrupt target text (Chinese)...how to fix it?

Dear colleagues,

I used to use a program called Unicode csv to resave bilingual Excel files before running it in Studio.  Unfortunately this program no longer works (with Windows 10?).

I was trying to create a TM from a client approved Excel file and found that I can't do it by opening the bilingual Excel file in Studio, because the Chinese text in target side is full of ???.  

Can someone tell me if there is a newer version of Unicode csv that will work?  Or if there is another easy way to create a TM from a bilingual file?  I know about making one file for source and one file for target and run the alignment, but this method is too time-consuming.

Thank you in advance for your suggestions.
