Add Byte order mark to the array header.

blob = new Blob(["\ufeff", description]);

URL.creatObjectUrl doesn't seem to work with raw UTF-8 strings. The solution provided for binary data https://stackoverflow.com/a/36955941/70716 should work. the answers to Creating a Blob from a base64 string in JavaScript also include some additional explanation of the issue and alternative code examples.
