  • ASCII: All ASCII characters, including 0-9, A-Z, a-z and special characters like $ , % + / : * etc
  • Auto: KeepAutomation's software will select proper data format according to your encoding value
  • Base256: to encode images, double-byte characters, binary data and 8 bit values
  • C40: numeric digits 0-9, upper-case letters A-Z
  • Edifact: 0-9, A-Z, many punctuation marks
  • Text: 0-9, a-z
  • X12: 0-9, A-Z, and some punctuation marks
