Comment (by azaozz):

 Thinking we should be more restrictive. Don't see a good reason to support
 anything except `[a-zA-Z0-9_-]+` for handles, both JS and CSS. To stay
 back-compat we can filter the handles on adding and using them, i.e.
 replace "unwanted" chars with dashes and throw "Doing it wrong".
