This: \[Backslash]0 null byte (code 0) \[Backslash].nn a character with hexadecimal code nn \:nnnn a character with hexadecimal code nnnn is copy/pasted from tutorial/CharacterCodes Sorry for the mixup on what page I was viewing, but as you see, the null byte coding is wrong, above. > emphasize, this is standard Unicode and system fonts here...nothing > specific to Mathematica). Everything I do is specific to Mathematica. (Or Photoshop Elements, Opera, MS Money, or Acrobat Standard 8.) No other tools here, my friend, Unicode or otherwise!
