As Qt WebKit based applications and browsers reach more corners of the globe (which speak "complex"/non-European scripts), 
the large number of text encoding and international domain names (IDN) related failing tests in Qt's Skipped list are painful to watch. 

I did a quick switch from QT4_UNICODE -> ICU_UNICODE and turned on CONFIG+=text_breaking_with_icu to maximize use of the ICU library, and the following list of Skipped tests ..

fast/encoding/char-encoding.html
fast/encoding/idn-security.html

fast/encoding/char-decoding-mac.html
fast/encoding/hebrew/csISO88598I.html
fast/encoding/denormalised-voiced-japanese-chars.html
fast/encoding/invalid-UTF-8.html


... shrinks to: 


fast/encoding/denormalised-voiced-japanese-chars.html    expected    actual    diff    pretty diff
fast/encoding/idn-security.html    expected    actual    diff    pretty diff
fast/encoding/invalid-xml.html    expected    actual    diff    pretty diff
fast/encoding/mailto-always-utf-8.html

I am also adding some bugs in the "Blocks" list which I think are solvable by this migration. Some may be dups of the above test failures.
