Switch type error #41

Closed lewispb closed 9 years ago

lewispb commented 9 years ago

Hi, I'm trying to switch type from B to C when creating a barcode. I've tried you're example code but get an error:

Barby::Code128A.new("ABC123\306def\3074567")

ArgumentError: invalid byte sequence in UTF-8

Could you please advise?

Thanks

you need to use ascii, not utf8:

"ABC123\306def\3074567".force_encoding('binary')

Thanks for your quick reply. That works fine. When I use this data though:

Barby::Code128A.new("\3072\306lgbrg\30761\306wg\30746000000".force_encoding('binary'))

What I'm trying to do is a form of length optimization. Do you know of any libraries or similar that would help with this? Thanks again.

Never mind, I've got it, found an issue that refers to this :) Would you like me to tidy up the github readme, maybe using Markdown?

Barby will automatically choose the most compact charset combination for you if you don't explicitly give one:

Barby::Code128.new('2lgbrg61wg46000000').full_data_with_change_codes => "2lgbrg61wg\xC746000000"
