Why does TextBlock trims ending spaces from the text?

Question

Here are my TextBlocks:

<StackPanel Orientation="Horizontal" Margin="0,3,0,0">
    <TextBlock Text="6 or more characters, at least one letter and a number,   "  FontFamily="Segoe UI" Foreground="#000000" FontSize="13"/>
    <TextBlock Text="no symbols"  FontFamily="Segoe UI" Foreground="#000000" FontSize="13"/>
</StackPanel>

And here is the output (screen shot):

Why does TextBlock trim ending spaces? However, it works fine when there are leading spaces.

Answer 1

It looks like xml:space="preserve" should do the trick (see Preserving Whitespace in XAML) but that doesn't seem to be working in a Windows Store app (it does in WPF).

If you use the non-breaking space character   it does work

 <TextBlock Text="6 or more characters, at least one letter and a number,&#160;&#160;&#160;&#160;&#160;&#160;&#160;"  ....

I suppose you could try building a converter on the Text property to check for trailing spaces and replace with non-breaking spaces - presuming the truncation that's happening doesn't occur too early.
