[[BOCU-1]] ('''Binary Ordered Compression for Unicode''') is a [[Unicode]] character encoding. It is associated with the ICU software, and apparently owned and [[Patents|patented]] by IBM. It is designed for small size (especially when encoding code points that are mostly from the same language), compatibility with [[MIME]] &amp;quot;text&amp;quot; media types, and to have certain desirable sorting characteristics.&lt;br /&gt;
&lt;br /&gt;
Despite its name, it does not have many of the attributes typical of a data compression format. It should probably be thought of simply as a Unicode encoding.&lt;br /&gt;
&lt;br /&gt;
See also [[SCSU]], to which it is sometimes compared.&lt;br /&gt;
