By contrast to the standard case folding functions such as
|
|
<function>strtolower</function> and <function>strtoupper</function>,
|
|
case folding is performed on the basis of the Unicode character
|
|
properties. Thus the behaviour of this function is not affected
|
|
by locale settings and it can convert any characters that have
|
|
'alphabetic' property, such as A-umlaut (Ä).

<para>
