Public bug reported:
Binary package hint: network-manager
(Hardy, up-to-date at the moment, last week of Mars 2008.)
Hello!
I've been traveling last week and I stayed at a hotel that had WiFi. I
noticed a weird problem. The access points had ESSIDs containing French
diacritics—"Hôtel de la Gare 1", etc. (it was a French hotel)—and I
couldn't connect to them using nm-applet.
In fact, nm-applet didn't display those ESSIDs at all. The problem might
be with wireless-tools or with the driver, though: I've had time to do a
bit of looking around. I used "iwlist scan" to check what was going on,
and it turns out that it could see the access points, but the 'ô'
character in the ESSID was displayed with an "unknown code-point"
symbol. However, my terminal is correctly configured to UTF-8 (I can
type the character, and 'cat'ing Unicode files with 'ô' works
correctly), so I suspected some encoding problems.
I did some logging (I'll attach the files next), which included
redirecting the output of the scan to a file. If I open the file with
Geany it detects the encoding as ISO-8859-1. I imagine "iwlist" (or
maybe the driver or some other component) doesn't do some charset
conversion it should do at some point. (Note that Windows laptops in the
same room could detect, display and connect to the APs.)
I could connect to the network by using "iwconfig ap [address] &&
iwconfig essid any", so the APs were probably working correctly.
This should be easy to test by setting the ESSID of your access-point to
"Hôtel" (encoded in various charsets, at least ISO-8859-1). Note that
the first file I attach was obtained by simply redirecting output of
commands while I was typing. So it should contain exactly the bytes
outputed by the applications.
(There are two attempts at connection in the log, the first time I
mistakenly connected to another AP I didn't have access to. There's some
screwing around with dhclient, too.)
