Mojibake (文字化け, moji character + bake ghost) is Japanese for broken characters: garbage that comes out when one tries to display international character sets through software not configured for them.
It is called luan ma (亂碼 or 乱码 luan4 ma3), or "chaotic code(s)", in Chinese.
Example: "文字化け" is displayed as "•¶Žš‰»‚¯"
