Alright then try words written in latin & random characters from different types of alphabets.

Seems pretty secure, but it's not over 8 characters...

If UTF8 was better supported, you could do something like

phone, snowman, snowman, pile of poo, phone.

That's fairly easy to remember and next to impossible to guess.

Great, now how do I use that password to log onto a mobile site from my phone? None of those characters are on my phone keyboard. Am I supposed to save them in a text file? That doesn't seem very secure.
