Getting the ? superscript in my blog title

Hi,

I’m trying to get the superscript TM at the end of my blog title here:

https://www.americastopplannerevent.com/

I’m using the Alexandria 2.0.17 theme. I cannot for the life of me get this to work. What’s crazy is using the ® at the end of my title shows the registered trademark symbol in the blog title in superscript just fine, but the ™ does not. Please help.
