account.hashMessage is incorrect with non-ASCII characters

[odanado]

Expected behavior

  const web3 = new Web3(null);
  const message = "🤗";
  console.log(web3.eth.accounts.hashMessage(message));
  // => 0xd21b04463b76fb09777ca0c59f4de0e02895b0847bf547b3df67ca7b67bb8f66
  console.log(web3.eth.accounts.hashMessage(web3.utils.utf8ToHex(message)));
  // => 0x716ce69c5d2d629c168bc02e24a961456bdc5a362d366119305aea73978a0332

Actual behavior

The two hash values should be the same.

I think you should use web3.utils.utf8ToHex on this line.

I found the same problem as you, and the solution you suggested works!

(I tested at ubuntu 18.04 / OSX 10.15.4 and node version is 13.5.0)
