In Javascript, many unicode characters are allowed [0], so háćḱéŕŃéẃś is a valid variable name [1].

Note: The number of іllэБіъlэVаѓіаъlэИамэѕ [2] used in your production code is inversely proportional to the number of friends you'll make in the maintenance team.

I had quite a lot of fun defining 汉字 variable names in C#. Though definitely not something to put into production code of course...
