When you browse some foreign sites, ie browser will prompt you to correctly display the page need to download XX language support. This is done by reading the Content-type property of the META tag of the HTML page and knowing which character set to use to display the page. If the corresponding character set is not installed in the system, ie prompts to download. Other languages also correspond to different charset, such as the Japanese character set is "ISO-2022-JP", the Korean is "ks_c_5601".
