<div><p>When you use the <span class="q">"root"</span> (/), QOpenSys, and user-defined file
|
||
|
|
systems, you can take advantage of system support that ensures characters
|
||
|
|
in object names remain the same.</p>
|
||
|
|
<p>This also applies when you use these file systems across <span class="keyword">iSeries™ server</span>s
|
||
|
|
and connected devices that have different character encoding schemes (code
|
||
|
|
pages). Your server stores the characters in the names in a 16-bit form that
|
||
|
|
is known as UCS2 Level 1 (that is also called <em>Unicode</em>) for *TYPE1 directories
|
||
|
|
and UTF-16 for *TYPE2 directories.
|
||
|
|
UCS2 Level 1 and UTF-16 are subsets of the ISO 10646 standard. When the
|
||
|
|
name is used, the system converts the stored form of the characters into the
|
||
|
|
proper character representation in the code page being used. The names of
|
||
|
|
extended attributes associated with each object are also handled the same
|
||
|
|
way.</p>
|
||
|
|
<div class="fignone"><span class="figcap">Figure 1. Keep characters the same across encoding schemes</span><br /><img src="rv3n141.gif" alt="Keeping characters the same across encoding schemes" /><br /></div>
|
||
|
|
<p>This support makes it easier to interact with a server from devices using
|
||
|
|
different code pages. For example, PC users can access an iSeries server
|
||
|
|
file using the same file name, even though their PCs do not have the same
|
||
|
|
code page as your server. The conversion from one code page to another is
|
||
|
|
handled automatically by your server. Of course, the device must be using
|
||
|
|
a code page that contains the characters used in the name.</p>
