    以前说过如果JS文件不是UTF8会在IE有bug,所以JS代码也要用UTF-8。还有数据库也都要用UTF-8。
php(做为现在的主流开发语言)用UTF-8总结:

  1. php(做为现在的主流开发语言)文件本身必须是UTF-8编码。不像Java会生成class文件,避免这个问题
  2. php(做为现在的主流开发语言)要输出头:header(”Content-Type: text/html; charset=UTF-8″)
  3. meta标签无所谓,有header所有浏览器就会按header来解析
  4. 所有外围都得用UTF8,包括数据库、*.js、*.css(CSS影响倒不大)
  5. php(做为现在的主流开发语言)本身不是Unicode的,所有substr之类的函数得改成mb_substr(需要装mbstring扩展);或者用iconv转码(基本上的linux都装了,没装的话download、tar、make、make install,很简单的)
  6. my.ini:
    [MySQL(和PHP搭配之最佳组合)]
    default-character-set=utf8
    [MySQL(和PHP搭配之最佳组合)d]
    default-character-set=utf8
    default-storage-engine=MyISAM
    在[MySQL(和PHP搭配之最佳组合)d]下加入:
    default-collation=utf8_bin
    init_connect=SET NAMES utf8
  7. 在需要做数据库操作的php(做为现在的主流开发语言)程序前面加上
    mb_internal_encoding(utf-8);
  8. create table最后边加上ENGINE=MyISAM DEFAULT CHARSET=utf8 COLLATE=utf8_bin
  9. php(做为现在的主流开发语言)MyAdmin/config.inc.php(做为现在的主流开发语言)
    $cfg[DefaultCharset] = utf-8;
    $cfg[RecodingEngine] = iconv;
  10. php(做为现在的主流开发语言)Admin导出数据时
    把"二进制区域使用十六进制显示"的勾去掉

特别郁闷的:文件系统函数不支持UTF-8!

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements.
