This font can be used to create an EAN-13 barcode which is a superset of the UPC-A barcode.
How to use
EAN-13 has 3 symbol sets A, B, and C. It looks like the following: *XXXXXX#CCCCCC*
* start/end bar (as common for Code 39)
# middle bar
X a symbol of set A or B (see below)
C a symbol of set C
The symbol sets are placed on an international keyboard layout:
Number row: 1234567890
Middle character row: asdfghjkl;
Top character row: qwertyuiop
The first digit of an EAN-13 barcode does not directly correspond to a symbol. It determines which symbol set for the following 6 digits is to be used. The following listing shows the symbol set combinations for the starting digits:
If the starting digit is 0, or if you want to encode a UPC-A, only use symbol set A.
The spaces are only inserted for clarity.
