+
+Designed by IBM for marking silicon wafers, each BC412 character is represented
+by 4 bars of a single size, interleaved with 4 spaces of varying sizes that
+total 8 (hence 4 bars in 12). Zint implements the SEMI T1-95 standard, where
+input must be alphanumeric, excluding the letter O, and must be from 7 to 18
+characters in length. A single check character is added by Zint, appearing in
+the 2nd character position. Lowercase input is automatically made uppercase.
