Likely it is the encoding of the merge file that is the problem.
I don't know if you needed the quote marks or not, so I stripped them. From Excel, I exported as a Unicode TXT file, which will automatically export as UTF-16 and is tab delimited. The result is shown below once merged.
Edit to add, make sure you are using an appropriate fonts, too
Have been resolved well as helpful.
I saved errors in Excel(Unicode TXT file)
