Subject: [PATCH 032/178] xcb: Fix drop of text/uri-list and text/html.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
When dropping URLs from Firefox or Chrome, the contents are encoded as
UTF16, but not correctly decoded. Moreover, the special handling of
"text/x-moz-url" drops does not work because this format is converted to
"text/uri-list" before. This fixes the handling for URL list and also
for UTF16 "text/html".
Task-number: QTBUG-47981
Change-Id: I1153f21ede07b2bfe4d104e0fe8bc8487ec5c165
