Which scripting language?

I'm writing a game. It will have a full level editor, so it needs an embedded scripting language for custom events.

Guile, Lua, or Python?

Guile and Lua fail at Unicode, which is a MAJOR drawback of both.
In games?
Yes, unless yours only ever prints "GO" and "HIGH SCORE".

Ever though of using JavaScript?
Piece of shit type system, massively flawed language, terrible design decisions, looks like a joke, failed lists, failed dictionaries, failed iteration, no standard library, low quality standard, sub-par interpreters. Other than that it's fine.
