String type is a problem in general with the new iOS VM - StringUtil.replaceAll() and backslash \

StringUtil.replaceAll() does not work on Strings with \\ generated from a 
Stream. I consume json data from a web service.

protected void readResponse(InputStream input) throws IOException {
    ByteArrayOutputStream bos = new ByteArrayOutputStream();
    Util.copy(input, bos);
    String s = bos.toString();
    s = StringUtil.replaceAll(s, "\\u0026", "&");

Similarly for json special characters:
"\\u0027", "'"
"\\u003c", "<"
"\\u003d", "="
"\\u003e", ">"

Anything characters appearing after double quote " (\\\") from json is 
truncated.

Works fine with the old iOS VM, android devices & the simulator.

When the string is built from code it works fine.
    String s = "This \\u0026 that.";
    s = StringUtil.replaceAll(s, "\\u0026", "&");

So backslash seems to be stored differently depending where it comes from.

The issue was actually in us using the \u internally to represent special 
characters and mistranslating that. So the stream got around fine but the 
hardcoded string was translated as & instead of as \u0026 so replace didn't 
work...
This should be fixed now, instead of using \u we are using ~~u as a shorthand 
internally which should see less conflict.
