Created Unassigned: Use Encoding.UTF8 instead of Encoding.Default [158]

When reading a source template, RazorGenerator currently uses `Encoding.Default`.

In `RazorHost.GenerateCode()`:


Stream stream = File.OpenRead(_fullPath);
using (var reader = new StreamReader(stream, Encoding.Default, detectEncodingFromByteOrderMarks: true))
{
results = engine.GenerateCode(reader, className: DefaultClassName, rootNamespace: DefaultNamespace, sourceFileName: _fullPath);
}

This can be easily tested by using the ellipsis (…) character in a template (ALT+0133), which gets transformed into:

WriteLiteral("�");

From Microsoft's [documentation][1] on `Encoding.Default`.

> Because all Default encodings lose data, you might use UTF8 instead.
