Subject: [PATCH] [Qt] Remove QT4_UNICODE related code paths
https://bugs.webkit.org/show_bug.cgi?id=108316
Reviewed by Kenneth Rohde Christiansen.
Source/WebCore:
Get rid of QT4_UNICODE and any related code paths. The Qt port
requires Qt5 and ICU these days. This also allows for the removal
of TextCodecQt.
* Target.pri:
* platform/KURL.cpp:
(WebCore::appendEncodedHostname):
* platform/graphics/SurrogatePairAwareTextIterator.cpp:
(WebCore::SurrogatePairAwareTextIterator::normalizeVoicingMarks):
* platform/text/TextEncoding.cpp:
(WebCore::TextEncoding::encode):
* platform/text/TextEncodingRegistry.cpp:
(WebCore::extendTextCodecMaps):
* platform/text/qt/TextCodecQt.cpp: Removed.
* platform/text/qt/TextCodecQt.h: Removed.
Source/WebKit/blackberry:
* WebCoreSupport/AboutDataUseFeatures.in: The feature macro has been removed.
Source/WTF:
Get rid of QT4_UNICODE and any related code paths. The Qt port
requires Qt5 and ICU these days.
* WTF.gypi:
* WTF.pro:
* wtf/unicode/Unicode.h:
* wtf/unicode/qt4/UnicodeQt4.h: Removed.
