Set superscript and subscript in formatted text in wpf

Question

How can I set some text as subscript/superscript in FormattedText in WPF?

Answer 1

Setting for superscript works fine with the following code:

<TextBlock Text="(cm"  />
<TextBlock ><Span BaselineAlignment="Top" FontSize="8">2</Span></TextBlock>
<TextBlock Text=")" />

Setting the Baseallignment for subscript in the Span tag did not work for me. I tried the following code and it worked fine.

  <TextBlock Text="H"  />
  <TextBlock Text="2" Margin="-2,0,-2,0" TextBlock.LineHeight="3" >   
  <TextBlock Text="O" />

Answer 2

It's interesting to note that for some characters (m², m³, etc) a superscript is not needed, but the unicode character can be used. For example:

<Run Text=" m&#x00B3;" />

This would show m³.
