equals 相同字符判断结果却不等

# 替换掉隐藏字符
vCodeForRedis.replaceAll("\\p{C}", "");
vCode.replaceAll("\\p{C}", "");

# 可以查看隐藏的字符长度；
char[] vCodeForRedisArray = vCodeForRedis.toCharArray();
char[] vCodeArray = vCode.toCharArray();
for (int i = 0; i < vCodeForRedisArray.length; i++) {
    System.out.print("["+vCodeForRedisArray[i]+"]");
}
for (int i = 0; i < vCodeArray.length; i++) {
     System.out.print("["+vCodeArray[i]+"]");
}
