Among the fonts in widespread use, [6] [7] full implementation is provided by Segoe UI Symbol and significant partial implementation of this range is provided by Arial Unicode MS and Lucida Sans Unicode, which include coverage for 83% (80 out of 96) and 82% (79 out of 96) of the symbols, respectively.
That is, characters with two wide elements use a 3:1 ratio, while characters with three wide elements use a 2:1 ratio, so all characters are 10 narrow elements wide (plus the inter-character space makes 11). "Rationalized codabar" uses a fixed ratio and allows the character widths to vary. Depending on the particular specification, for example ...
