For some reason my WiFi notifications have started appearing in I think Polish, or something with a similar alphabet, I don't even have any such languages installed as far as I can see.
This problem has survived through an update to 4.3 Jelly Bean. Phone is Galaxy Note 2, (GT-N7100), on O2 UK.
The 3 messages that I get when turning WiFi on and off with my home network - which has an English name, are in the attached picture.
Google Translate tells me that they are Polish for "Available connectivity package", "No access to Network" & "Available Wi-Fi connectivity".
