Hi, what's the meaning of Code128Auto in fontpal tool? There are five fonts (MRV Code128XS, MRV Code128S, MRV Code128M, MRV Code128T, MRV Code128XT), they have no character set (A, B or C), what the meaning of this?

Code128 is capable of encoding all 127 characters from 0~127 but Code128 only has 107 unique patterns.

Code128Auto automatically shifts from one character set to another if necessary.

Code128XS, S, M, T, XT corresponds to XSA, SA, MA, TA and XTA versions of the character set A, B, C. The pattern is the same so it is not necessary to make 3 non-human readable font sets.

The human-readable versions must have 3 sets since the human readable is different.

So, if you encode with Code128BMA, the counterpart non-human readable typeface will be Code128M. If you encode with Code128CMA, the non-human readable typeface is also Code128M.

Code128 is a relatively complicated symbology. More information can be found here:

does your font support SHIFT and CODE A, CODE B, CODE C chars?

Our font contains alll Code128 patterns. Character mapping can be found at:

But... if there is a CODE B char, for example, the code 128 data sting will have two data set. Possible?

Yes. It is possible. Actually it is how Code128 encodes all 0-127 ASCII characters. Our Code128Auto function insert CODE start character automatically if the character encountered can not be encoded using the current char set.
