I came across this helper function to find a string length present at https://github.com/ensdomains/ens-contracts/blob/master/contracts/ethregistrar/StringUtils.sol And I couldn't understand what this piece of code is doing uint bytelength = bytes(s).length; for(len = 0; i < bytelength; len++) { bytes1 b = bytes(s)[i]; if(b < 0x80) { i += 1; } else if (b < 0xE0) { i += 2; } else if (b < 0xF0) { i += 3; } else if (b < 0xF8) { i += 4; } else if (b < 0xFC) { i += 5; } else { i += 6; } } return len; Any help is appreciated. Thank you
