encoded. Trying to encode illegal (or not supported data) will result in a "Data

<p>The name comes from the that each data character is composed of 5 elements,
either 5 bars or 5 spaces. Two elements are 3 modules wide and three elements
have a width of 1 module. Adjacent characters are interleaved, mixing the spaces
from one character with the bars of the other.</p>

<p>This is also known as "<span class="italic">Code 3 of 9</span>" or

are 2 modules wide and the rest one module wide. Code 39 is defined in <span class="italic">American National Standards Institute</span> (ANSI)
standard MH10.8M-1983.</p>
<p>The full 128 ASCII character set can be encoded in Code 39. </p>
<p>Code 39 is a very widely used barcode and basically every scanner/reader on
the market is able to decode Code 39 barcodes which makes it for a very good
selection as a generic linear barcode.</p>
