Are you sure the Buffer.byteLength call is what you want here? It will coerce the length to a string, then give you the length of that.

These characters are all within the latin-1 charset. check via
Buffer('¡hèlló wôrld!','binary').toString('binary') === '¡hèlló wôrld!'Mind using a two byte utf-8 character?

OK, changed the è to an έ.

TODOcomment in the tests.Thing is, I'm not sure this is really needed. There seem to be things in other places in this test file that would trigger
utf8Slice(), at least on casual inspection.So...@chrisdickinson: I know you ran some code coverage analysis recently. Any chance you could run code coverage on just the one file that's changed here and compare it to the results with the version in master to see if this change results in slightly more coverage? Or point me at the code coverage tool you used and I'll try to get up and running with it to do this myself?
