* Available in 5 programming languages, all with nearly equal functionality: Java, JavaScript, Python, C++, C
* Significantly shorter code but more documentation comments compared to competing libraries
* Supports encoding all 40 versions (sizes) and all 4 error correction levels, as per the QR Code Model 2 standard
* Output formats: Raw modules/pixels of the QR symbol (all languages), SVG XML string (all languages), BufferedImage raster bitmap (Java only)
