This was:

• fixed by [chore] Use wtf-8 instead of utf8 to prevent lone surrogates from gen… engine.io-parser#68, released as engine.io-parser 1.3.0
• included in engine.io with [chore] Bump engine.io-parser to 1.3.0 engine.io#425 and released as 1.7.0
• and finally included in socket.io with package: bump engine.io #2707, included as 1.5.0
