maybe worth putting unicode in the comment, it looks like some tools care about this.

That doesn't actually matter much if Unicode characters in comments are encoded properly in Node's binary, if that's what you are talking about, IMO, though they may be useful for debugging, as @Fishrock123 noted. It is quite easy to test Unicode in comments automatically, either exporting a function with a comment inside in this module and checking fn.toString() in the test, or checking the whole value of process.binding('natives')['internal/test/unicode'], but I'd like the status of #11371 and #11417 to become clear before doing this so that this part of the test won't become obsolete as soon as either of these lands (if any). Not to mention that I don't think it is necessary to test Unicode in comments specially at all: how are they different from any other parts of the source code?
