WPF TextWrapping on white spaces

问题

I am using a TextBlock in WPF, on which I want to use TextWrapping, What I have done in XAML is as follows.

<TextBlock TextWrapping="Wrap" Grid.Column="0" Grid.ColumnSpan="4" Grid.Row="0" Margin="5,5,5,5">
                                <TextBlock.Text>
                                    This is just a test. This is just a test.
                                </TextBlock.Text>
                            </TextBlock>

When I run this code it shows output like this

This is just a test. Th
is is just a test.

But I only want wrapping on white spaces like

This is just a test.
This is just a test.

I am unable to find why WPF is showing this behavior, I have tried WrapWithOverflow and IsHyphenationEnabled=true with no success. Please help me out?

Bizz is right, this shouldn't be the behavior of Text Wrapping, Just a wild guess, are you copy/pasting text from some where to Visual studio? there might be an issue with white spaces in that case, and WPF will wrap your text in wrong way.
