One of the great areas of maturation is in -the focus that has been given over the past decade to make it possible for anyone -anywhere to use a computer. It has not always been that way, in fact, not so long -ago it was common for software to be written for exclusive use in the country of -origin. -</p><p> -Of all the effort that has been brought to bear on providing native language support -for all computer users, the efforts of the Openi18n organisation is deserving of -special mention. For more information about Openi18n please refer to: -<a href="">http://www.openi18n.org/</a>. -</p><p> -Samba-2.x supported a single locale through a mechanism called -<span class="emphasis"><em>codepages</em></span>. Samba-3 is destined to become a truly trans-global -file and printer sharing platform. -</p></div><div class="sect1" lang="en"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a name="id2997167"></a>What are charsets and unicode?</h2></div></div><div></div></div><p> -Computers communicate in numbers. In texts, each number will be -translated to a corresponding letter. The meaning that will be assigned -to a certain number depends on the <span class="emphasis"><em>character set(charset) -</em></span> that is used. -A charset can be seen as a table that is used to translate numbers to -letters. Not all computers use the same charset (there are charsets -with German umlauts, Japanese characters, etc). Usually a charset contains -256 characters, which means that storing a character with it takes -exactly one byte. </p><p> -There are also charsets that support even more characters, -but those need twice(or even more) as much storage space. These -charsets can contain <b class="command">256 * 256 = 65536</b> characters, which -is more then all possible characters one could think of. They are called -multibyte charsets (because they use more then one byte to -store one character). -</p><p> -A standardised multibyte charset is unicode, info is available at -<a href="http://www.unicode.org/" target="_top">www.unicode.org</a>. -A big advantage of using a multibyte charset is that you only need one; no -need to make sure two computers use the same charset when they are -communicating. -</p><p>Old windows clients used to use single-byte charsets, named -'codepages' by Microsoft. However, there is no support for -negotiating the charset to be used in the smb protocol. Thus, you -have to make sure you are using the same charset when talking to an old client. -Newer clients (Windows NT, 2K, XP) talk unicode over the wire. -</p></div><div class="sect1" lang="en"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a name="id2997235"></a>Samba and charsets</h2></div></div><div></div></div><p> -As of samba 3.0, samba can (and will) talk unicode over the wire.
