Superfish Submenu Indicator Arrow Won't Display When js/css Aggregation Turned On

I have exactly the same problem. Only on the taxonomy terms pages. With js aggregation enabled.
A message appears in the console:
Uncaught ReferenceError: assignment to undeclared variable p
The solution described in #7 does not help.

#6 doesn't really work. As soon as you flush the cache again the down arrows disappear again. Why doesn't some fix this? I'm using Drupal 10 and the same problem occurs.

I have tried to reproduce this issue different ways, but unfortunately I can't. They only thing I noticed, we are missing arrows just a sec and then when CSS is applied they correctly displayed and once it is cached then they appear immediately.

Could you provide more information how to reproduce it?
What version is used and etc. ?

I think, I found the problem and sometimes it was broken for me too. The cause of the problem was in special symbols used directly in CSS:

content: "►";

When aggregation happens, these symbols are not correct encoded. So, the proper way to use UTF codes instead:

content: "\25BA";

I will add fix in the next version of the library.

Thank you for your contribution
