  • For the overall system
  • For each unique contract within the system
• Clean code
  • Run a linter (like EthLint)
• Fix compiler warnings

"""
Use Unicode flag emoji homoglyphs to re-encode UTF-8.

To encode, a string is first encoded as UTF-8, then each byte is
broken down into bits, and each bit is encoded as a flag:
The more well-known country flag in each pair represents 0, and the
less well-known one represents 1. Pairs are cycled through.

There are 8 pairs total, which is the most I could find without repeats.
