Non-English Barcode Value
Most 1D barcodes encode a subset of ASCII character set. Code128 extends encoding to ISO-8859-1 character set by using the special symbol FNC4.
2D barcodes (PDF417, DataMatrix, QR), on the other hand, are capable of encoding text in any language. All output formats use UTF-8 encoding to accurately represent non-English file names and barcode text values. Localized language text can be encoded in the barcode in several ways:
Type | Generation process | auto-detection |
UTF8 | Text is encoded as UTF-8 before barcode generation | yes |
ECI | Barcode generator uses Extended Channel Interpretation | yes |
Generator | The Barcode generator encodes text according to barcode type specification, e.g., KANJI for QR code. | yes |
CodePage | Text encoded using language-specific code page before barcode generation. | no |
The barcode recognition engine automatically detects and outputs the UTF-8 barcode values for UTF8, ECI, and Generator types.
To get the UTF-8 value for CodePage-encoded value, your application should explicitly decode Data value.
NOTE: Using incorrect codepage barcodes results in an incorrect output text value.
