AP name not necessarily valid UTF8

[era]

Binary package hint: wifi-radar

Stumbling over an access point with invalid UTF-8 in its name produces this warning:

/usr/sbin/wifi-radar:798: PangoWarning: Invalid UTF-8 string passed to pango_layout_set_text()

There is no requirement that access point names be valid UTF-8 (in fact, this one was valid Latin-1 "nätverk" or some such) so the strings should not be displayed untranslated.

http://lists.apple.com/archives/macnetworkprog/2006/Nov/msg00026.html and an informal perusal of the documents via ieee802.org seems to confirm that there is no firm standard on this. (However, bug #27171 would seem to allege that Latin-1 is in fact the standard. I seriously doubt this, though.)
