Hey Didier,

thanks for your comment! Meanwhile, I'm on 4D (great, smart, faster, obsolete, grey-haired old fashioned ones have fun with it, just as me) but it's always nice to read some FRESH comments!

If anyone is concerned with the licensing of the ID Automation fonts I can confirm that this encoding works just fine with the font available here:

Many thanks for this CF, I wasn't looking forward to hacking one together myself.

Hi, I am using the IDAutomation Code128 plugin in our filemaker database (FM11 pro) Windows 8 SP1 {4digit code} and it seemed to work all fine over the last year or two. I am doing stocktake today and the following 4 digit numbers print as a "?"


All other 4 digit numbers (from 0001 - 9999) print fine. I havent changed anything (same font same layout same character size) Label machine is DYMO labelwriter 450, but this id not the culprit as it shows already up as a "?" in Filmaker.

Any idea, pointing in a directionor other help is much apprechiated.
I am really confused about it.

Getting mixed results using the free Code 128 True Type font.
This great function get it almost always right (as in 1977.2), failing in some 1% of times (as in 1977.3 or in 2002.37), stamping a big "Â" just before the stop bars.

Any ideas?
