The source code viewer does not respect the encoding of the file

The Linguist source code viewer does not respect the encoding of the file as it always loads it as latin1.

tools/linguist/linguist/sourcecodeview.cpp:

fileText = QString::fromLatin1(file.readAll());

Steps to reproduce:

The sourcefile is saved in UTF-8 and some unicode character is used, for example:

setText(tr("variable χ"));

Create translation file:

lupdate example.pro -codecfortr UTF-8 -ts example.ts

Open the file in Linguist

linguist example.ts

Result: Unicode character is not shown correctly
