Description

At the moment CharSequenceResource#getLength() looks like:

@Override
	protected Long getLength(CharSequence data)
	{
		return (long) data.length();
	}

This returns wrong results when there are unicode symbols like "\u1234".

It should use org.apache.wicket.util.string.Strings#lengthInBytes() instead.
