  • ToCharacterCode[" string "] 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.
  • See the Mathematica book: Section 2.7.7.
  • See also: FromCharacterCode, Characters, CharacterRange, $CharacterEncoding, DigitQ, LetterQ, InputForm.

    This converts the string to its ASCII character code equivalents and back again.
