Tpk failed upload

Tpk failed upload

I’m trying to upload a tpk to Tizen seller portal. I get the error shown in attachment. lt says something about UT characters in a file name in the binary. I used the watch calculator sample and the only file I added was all ASCII characters. Specifically , I used an underscore. Can anyone make a suggestion about what I should look for. Thanks.
