<div><p>Some characters can be made up of more than one Unicode character.</p>
|
||
|
|
<div class="section"><p>For example, characters that have an accent
|
||
|
|
(for example, é or à) or an umlaut (for example, ä or ö) need to be changed,
|
||
|
|
or <em>normalized</em>, to a common format before they are stored
|
||
|
|
in the directory, so that all objects have a unique name. Normalizing a combined
|
||
|
|
character is a process by which the character is put in a known and predictable
|
||
|
|
format. The format chosen for *TYPE2 directories is the <em>canonical composed
|
||
|
|
form</em>. If there are two objects in a *TYPE1 directory that contain the
|
||
|
|
same combined characters, they are normalized to the same name. This causes
|
||
|
|
a collision, even if one object contains composed combined characters and
|
||
|
|
the other object contains decomposed combined characters. Therefore, one of
|
||
|
|
them has its name changed before it is linked in the *TYPE2 directory.</p>
