The glyph you saw is from the "Last Resort" font, and is a generic  
glyph representing the supplementary math alphabets. Apple Mail  
understood the character (as I'd expect), but you didn't have a font  
that could display it; so the system used this as a fallback. If you  
were to install a font that actually supports that character, you'd  
see the Fraktur W as I entered it. (There aren't many such fonts  
around, though! James Kass's "Code2001" is one that's available, if  
interested.)
