how to install adobe reader korean language support package

The PDF document contains data in Japanese and needs the support package to display the correct Japanese characters. This is common with files on websites of Japanese companies even thought the document may contain English language also. You can simply cancel and then view the document English text but the Japanese text will not be displayed and you will see various garbage and blank spaces instead. Alternatively, you could simply install the support package. This will then enable Acrobat reader to correctly display Japanese characters.
