gives a list of the integer codes corresponding to the characters in a string.

ToCharacterCode["string", "encoding"]
gives integer codes according to the specified encoding.


  • ToCharacterCode handles both ordinary and special characters.
  • ToCharacterCode["string"] returns standard internal character codes used by Mathematica, which are the same on all computer systems.
  • For characters on an ordinary American English keyboard, the character codes follow the ASCII standard.
  • For common European languages, they follow the ISO Latin-1 standard.
  • For other characters, they follow the Unicode standard.
  • Mathematica defines various additional characters in private Unicode space, with character codes between 64256 and 64300.
  • Character codes returned by ToCharacterCode["string"] lie between 0 and 65535.
  • Encodings supported in ToCharacterCode["string", "encoding"] are listed in the notes for $CharacterEncoding.
  • If a particular character has no character code in a given encoding, ToCharacterCode returns None in place of a character code.
  • ToCharacterCode[{"s1", "s2", ...}] gives a list of the lists of integer codes for each of the .
