The non-quoted symbol format follows the same naming rules as variables (local, instance, class, global), methods, and constants (Modules, Classes, and Constants). Otherwise, you'll have to resort to the quoted string format.

Also, notice that:
~~~
:foo == :'foo' # => true
~~~

Currently it is not possible to create a symbol that looks like `:1twothree`.

Converting to a string and then symbolizing causes hash lookup problems and proves counter-intuitive. What's also surprising is that ruby allows symbols to start with special characters but not numbers.
