tl;dr: Libre Barcode is a collection of free fonts for rendering Code 39, Code 128, and EAN/UPC barcodes, with optional human-readable text. The project includes an online Code 128 Encoder that converts input text into properly encoded strings usable with the Libre Barcode 128 fonts.
HN Discussion:
  • Barcode fonts are a bad approach; use native printer support or vector generation instead
  • Appreciates the project's automatic checksum calculation for EAN13 as a useful feature
  • Limited usefulness because users still need to calculate checksums and handle complex encoding themselves
  • Enthusiastic appreciation for the font project and similar creative font endeavors
  • Questions and curiosity about barcode standards, encoding details, and comparisons to QR codes
