Add Unicode/special characters support to enhance Metamask security

Description: Password provides good protection against hackers, but MetaMask can make it more secure by adding support for Unicode/special characters. The inclusion of Unicode will make it harder for hackers to hijack a wallet, forcing them to try larger number of character sets and possible combinations, thus decreasing the likelihood of a wallet getting brute-forced by unauthorized party.

Purpose: To enhance the security of the MetaMask wallet.
