Hi @gpongelli! Do you have an example of a string that fails?

[gpongelli]

sure!
take a look at this barcode

you can find it into the QuickScan QD2200 Product Reference Guide, page 25.
the label, expressed using this library's input, is [FNC3]RevA\r:

• using the actual master's commit, the above string will exit with "invalid character in string" due this if block, even if estimate_length's return value is not zero
• using this fix, the above string will correctly generate the label

FYI this changes works only on windows.

on raspberry hw, I still get "Invalid characters in string".
