Japanese Industrial Standards
The Shift JIS character set is a Japanese Industrial Standards (JIS) superset of JIS X 0201 (in turn almost a superset of ASCII) intended for Japanese usage. Unlike Western ASCII art, which is generally designed to be viewed with a monospaced font, Shift_JIS art is designed around the proportional-width MS PGothic font supplied with Microsoft Windows, which is the default font for web sites in Japanese versions of Windows. This dependency has led to the development of the free Mona Font, in which each character is the same width as its counterpart in MS PGothic. This is useful on operating systems lacking the PGothic font, such as Linux.
