Seems Firefox doesn't decode the URL when there's url-encoded non-ASCII characters.
For me no Window opens, for some in the test case, the body is stripped.
Both links are opened in Thunderbird here, but the first one doesn't have a body.

After a further research, it seems Firefox treat encoded characters as UTF-8, since %E2%82%AC work but not %80.

Could it be related to bug 647403 and the removal of network.standard-url.encode-query-utf8 ?
