Why French word of url cannot be parsed by Node.js V6?

I meet one issue, this url 'localhost:4020/share/Fr?chars=ECYCÉDN' with French word can NOT be parsed in Node V6.10.0, however it could be parsed correctly under Node V0.10.42.

Here are more details for my codes

• The middleware for Express

  app.use bodyParser.urlencoded({ extended: false })
  app.use bodyParser.json({ limit: '20mb' })
  app.use bodyParser.urlencoded({ limit: '20mb', extended: false })
  
  

• And output the chars in the above url router

  console.log(req.query.chars)

I test this server with curl 'localhost:4020/share/Fr?chars=ECYCÉDN', and the results are

• Node v0.10.42

  {"chars":"ECYCÉDN"}

• Node v6.10.0

  {"chars":"ECYCÃ DN"}

I want to know why this French word cannot be parsed correctly under Node V6.10.0?

I think it could be the character encode issue. However, I try to use querystring.unescape or querystring.escape of querystring, it does not work well.
