About ANSI (discover EditPlus) The default is this Code __ encoding

To enable the computer to support more languages, you typically use the 0x80~0xff range of 2 bytes to represent 1 characters. For example: Chinese characters ' in ' in the Chinese operating system, using [0xd6,0xd0] These two bytes of storage. Different 
  countries and regions have developed different standards, resulting in GB2312, BIG5, JIS and other coding standards. These use 2 bytes to represent a character of a variety of Chinese character extension encoding, called ANSI encoding. Under the Simplified Chinese system, ANSI encoding represents GB2312 encoding, and in Japanese operating system, ANSI encoding represents JIS code.
  different ANSI encodings are incompatible, and when information is exchanged internationally, text that is in two languages cannot be stored in the same piece of ANSI-encoded text.

Because we write the HTML is written in EditPlus, and then he used the default encoding is ANSI, and then if you use Apatana to open it will be garbled (default is UTF-8), this time, you need to save in EditPlus, do not change the name, the code rule is ok
