RFC 2152                         UTF-7                          May 1997


               Character   ASCII & Unicode Value (decimal)
                  '           39
                  (           40
                  )           41
                  ,           44
                  -           45
                  .           46
                  /           47
                  :           58
                  ?           63

      Set O (optional direct characters) consists of the following
      characters (note that "\" and "~" are omitted):

               Character   ASCII & Unicode Value (decimal)
                  !           33
                  "           34
                  #           35
                  $           36
                  %           37
                  &           38
                  *           42
                  ;           59
                             62
                  @           64
                  [           91
                  ]           93
                  ^           94
                  _           95
                  '           96
                  {           123
                  |           124
                  }           125

   Rationale. The characters "\" and "~" are omitted because they are
   often redefined in variants of ASCII.

   Set B (Modified Base 64) is the set of characters in the Base64
   alphabet defined in RFC 2045, excluding the pad character "="
   (decimal value 61).
