The invention discloses a cross-platform Chinese character messy code recovery method. The method is characterized by comprising the following steps: acquiring coding formats of a sending platform and a receiving platform; identifying Chinese characters and non-Chinese characters of the sending platform, wherein the non-Chinese characters divide a Chinese character set into a plurality of Chinese character strings; performing even conversion treatment on each Chinese character string in sequence, wherein according to the even conversion treatment, Chinese characters to be converted are adjusted as an even number of characters. The cross-platform Chinese character messy code recovery method has the advantages that according to the coding types of the sending platform and the receiving platform, adaptive even conversion treatment is performed, and redundant bytes are eliminated after transcoding, so that the problem of messy codes is solved, and the experience of a user is greatly improved.
