Details

Japanese strings are often made up a mixture of Chinese characters (Kanji), Kana (Hiragana and Katakana) and Romaji (Latin phonetical pronunciation). The external program kakasi converts between these four different ways of writing Japanese. The function wraps the external program kakasi with system(). The kakasi program must be present and on the user's PATH for the function to work. kakasi is useful especially for sanitizing a character vector by converting Japanese (non-ASCII) to ASCII characters.
