(Doing some stuff in beamer today!)

I'm trying to include a star in some beamer output, using xelatex or 
lualatex as the pdf engine. I'm getting errors like this:

```
[WARNING] Missing character: There is no ★ (U+2605) (U+2605) in font 
[lmsans10-regular]:mapping=te
```

I've tried changing the main font to something that I think has these 
characters (like Helvetica or Times), but no luck.

Is there some latex thing going on, or do I just not understand what's 
going on. Reveal.js output is fine, for example, and I can put the 
characters into a simple html file using a style attribute for those 
font-families.

TIA.

"I think" is no guarantee... :-) Besides, Times is only good for its original
purpose (narrow newspaper columns) and presentations shouldn't use serif fonts
anyway. :D

Personally, I'm partial to Libertinus Sans, but for something more
down-to-earth, you might consider DejaVu Sans.

I'm pretty sure Reveal.js uses a font with good Unicode support.

It could be that your browser uses some fall-back fonts for characters that are
not in the requested font.

Or it could be that you indeed have a LaTeX problem. In that case it would help
to use pandoc to create the .tex file and then run latex on it yourself. You'll
get a .log file that should tell you (or us) more.

Nope.

The error in the log file is the same that pandoc outputs (this time tried 
Courier):

```
Missing character: There is no ⋆ (U+22C6) in font 
Courier/AAT:mapping=tex-text;
!
```
Happy to post the whole thing, if that would help. (Again, not a latex guy.)

This happens if I use \pi too. Iʻm pretty sure the fonts Iʻm using have 
these characters.
