你知道 Node.js 有什么好的 Buffer 检查库吗？将 Buffer 及其 utf8 内容打印出来会非常有用。例子：

Byte | HEX | UTF-8 | Name
-----+-----+-------+-----------
   0 |  48 | H     | UPPER H
   1 |  65 | e     | LOWER E
   2 |  6c | l     | LOWER L
   3 |  6c | l     | LOWER L
   4 |  6f | o     | LOWER O
   5 |  20 |       | WHITESPACE
   6 |  57 | W     | UPPER W
   7 |  6f | o     | LOWER O
   8 |  72 | r     | LOWER R
   9 |  6c | l     | LOWER L
  10 |  64 | d     | LOWER D

昨天我做了一个简单的模块，叫做hex。这就像 hxd 程序。无需配置，易于使用，用于调试目的。

var hex = require("hex");
hex(buffer);

输出：

Offset   00 01 02 03 04 05 06 07 08 09 0A 0B 0C 0D 0E 0F
