Code 39/3 of 9 FullAscii
Character set: All 128 characters of the "simple" ASCII table.
The characters have the same structure as with "Regular Code39 / 3 of 9", only that "toggles" are used in front of the characters. An "a" is achieved, for example, by placing a "+" in front of an "A" in the code. The correspondingly configured reader will then interpret the string “+ A” as “a”.
