+ \section2 ICU
+
+ Qt WebKit, and applications using it, always need the ICU libraries. Qt Core
+ can be configured to either rely on ICU functionality, or fall back to Windows API
+ and internal algorithms with somewhat reduced functionality.
+
+ From Qt 5.3 and onwards, configure does not link Qt Core against ICU libraries
+ anymore by default. This reduces the size of a self-contained
+ application package considerably, as long as Qt WebKit is not used.
+
+ Letting Qt Core utilize the ICU libraries however has following advantages:
+ \list
+ \li Behavior matches other platforms more closely.
+ \li Extended set of text codecs (see \l QTextCodec).
+ \li QLocale::toUpper(), QLocale::toLower() always use case conversion rules
+ specific to the locale.
+ \li QCollator::setNumericMode() does work consistently on all Windows versions.
+ \endlist
+
+ To explicitly enable the use of ICU in Qt Core, pass \c -icu to \c configure:
+
+ \code
+ configure -icu
+ \endcode
