Addendum: to clarify, with "non-degenerate input" I mean that for the vast majority of nodes in the resulting trie we have a handful of charCodes to search through at most. This holds true for most normal types of text. It is however trivial to create string that breaks this assumption: make one that features every legal UTF16 charCode. Throwing this at lzstring-unsafe.js will freeze it. So this could be another assumption that does not hold for uBlock's use case.
