Character8

  • Import can read any file as a sequence of characters.
  • Export writes a list of characters to a file.
  • Background & Context

      Sequence of 8-bit characters.
      Raw binary format.

    Import and Export

    • Import["file","Character8"] imports any file, returning a list of 8-bit characters.
    • Export["file",list,"Character8"] exports a list of characters to a binary file.
    • Export["file",expr,"Character8"] converts an expression to a string of characters and exports it to a binary file in which each byte represents a character.
    • Import["file",{"Character8",elem}] or Import["file",elem ] imports the specified element.
    • Import["file",{"Character8",{elem1,elem2,}}] imports multiple elements.
    • See the reference pages for full general information on Import and Export.
    • ImportString and ExportString support the Character8 format.

    Elements

    • General Import elements:
    • "Elements" elements and options available in this file
      "Rules"full rules for each element and option
      "Options"rules for options, properties, and settings
    • Data representation element:
    • "Data"list of 8-bit characters
    • By default, Import and Export use the "Data" element.
    • Import["file",{"Character8",n}] gives the n^(th) byte.

    Options

    • Import option:
    • "HeaderBytes"0how many bytes to skip at the beginning of the file

    Examples

    Basic Examples  (2)

    Convert a list of characters to a string representing an 8-bit character array:

    In[1]:=
    Click for copyable input
    Out[1]=

    The Wolfram Language can also convert expressions of multicharacter strings to 8-bit characters:

    In[2]:=
    Click for copyable input
    Out[2]=

    Convert the previous result back to an expression:

    In[3]:=
    Click for copyable input
    Out[3]=

    Multibyte characters cannot be exported to the Character8 format:

    In[1]:=
    Click for copyable input
    Out[1]=
