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
Symbol sets
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:
- AABABB
- AABBAB
- AABBBA
- ABAABB
- ABBAAB
- ABBBAA
- ABABAB
- ABABBA
- ABBABA
If the starting digit is 0, or if you want to encode a UPC-A, only use symbol set A.
Examples
The spaces are only inserted for clarity.
- EAN number → symbol set → What you type with the font
- 2 012345 67890 3 → *AABBAB#CCCCCC* → *01sd4g#yuiope*
- 2 230154 67890 1 → *AABBAB#CCCCCC* → *23;a5f#yuiopq*
- 9 786789 12345 1 → *ABBABA#CCCCCC* → *7kh7k9#qwertq*
- 9 789876 12345 7 → *ABBABA#CCCCCC* → *7kl8j6#qwertu*
The above examples contain all symbols, try them.
