For those of you who use the Vuze BitTorrent client (formerly known as Azureus), you may have come across this interesting quirk whereby most of the menus, tabs and other key texts within the client window change to an unintelligible font as follows:

This is caused by the client losing its language settings. You’re looking at the Armenian language. To fix this, simply:

1. Go to the fifth menu (which is the Tools menu).
2. Select Configuration Wizard from the menu and a window appears.
3. Change the language to the language you prefer, eg: English, and all of a sudden all windows will suddenly appear correctly again.
4. Click Cancel to close the window (there’s no need to go through the entire configuration wizard).

Problem solved!
