Answer 1

I've built a library traditional-or-simplified to detect if a string contains a majority of Traditional or Simplified Chinese characters by comparing the number of Simplified/Traditional characters that appear in an input string.

var TradOrSimp = require('traditional-or-simplified');

// Detect if a string contains Simplified Chinese 
TradOrSimp.isSimplified('无需注册或设置')
// True 

// Detect if a string contains Traditional Chinese 
TradOrSimp.isTraditional('無需帳戶或註冊。')
// True 

// Detect if a string contains Traditional or Simplified Chinese characters 
TradOrSimp.detect('無需帳戶或註冊。')

/* 
{ inputLength: 8, // Length of input string 
  simplifiedCharacters: 0, // Count of Simplified Chinese characters 
  traditionalCharacters: 4, // Count of Traditional Chinese characters 
  detectedCharacters: 'traditional', // Detected character set 
  detectionRate: 1 } // Ratio of majority/minority character sets */
