The iSCSI standard says that target names are Unicode (encoded in UTF-8). But this initiator gets confused when a target name contains non-English characters. It's not a large problem but it's a bit ugly.
For example, I have a target named iqn.2001-05.com.equallogic:8-cb2b76-4a1b5a01a-cb80000003455032-日本語.
The initiator shows it as iqn.2001-05.com.equallogic:8-cb2b76-4a1b5a01a-cb80000003455032-日本語
So it looks like it is misinterpreting the UTF-8 encoded data as if it were Latin-1 or some similar single byte character set.
