The purpose of this paper is to avoid the garbled problem caused by the use of UTF-8 encoding, which does not contain the specific garbled solution and the content of the code conversion. For an in-depth understanding of UTF-8 coding, refer to: "Regular expressions for text characters in PHP matching UTF-8"
1, Editor: Do not use any Microsoft editor, what Frontpage,web Designer, Notepad, WordPad and so on, can throw away all, because these editors will be in front of your UTF-8 document generated BOM, the specific description of the BOM, can be found here, That year I directly to the Notepad to UTF-8 overwrite the original file, causing a lot of code damage, still fresh memory.

3. PHP:
Use the MB library and do not use the Iconv library.
Use Preg instead of using Ereg to handle characters.
With the Htmlentities () function, the Html_entity_decode () function takes a third argument:
$str = "Chinese";
Echo htmlentities ($str, Ent_compat, "UTF-8"); Display (inside the source code) <a href= ' Test ' > Juan?
