Setting the encoding in the basic auth header

As a further follow-up, see

https://bugzilla.mozilla.org/show_bug.cgi?id=41489

They explain that *TEXT is defined in RFC 2616, which specifies
that non-ASCII characters must be MIME-header-encoded. So
0BA4 should be encoded as '=?utf-8?b?4K6k?=', according to
the specification. No browser currently implements that.
