x^2 shows as superscript in plaintext mails but copies as x2

When I receive an email with a text/plain attachment that contains the text 'x^2', Thunderbird nicely displays the code with a superscript '2' in place of the regular text '^2'. This makes reading things like mathematical expressions a bit nicer, so it's a good thing.

Problem is that when I highlight such text and copy it to my text editor, I get 'x2' instead of x^2'. This means that I can't safely copy code attached to an email!

When this superscript text trick is used, Thunderbird should be using something along the lines of the <IMG ALT=...> mechanism to ensure that plaintext is copied as originally entered.


Reproducible: Always

Steps to Reproduce:
1. Write email with x^2 in it
2. Send it to yourself.
3. Copy the text to gedit
4. See that you have 'x2' instead of x^2
Actual Results:  
x2

Expected Results:  
x^2
