Are unicode characters required in the title?

Question

Search Engine Optimization

Hello,
Who has experience of how users and search engines react to the symbol () at the beginning of the title?
I plan to put one character before the main text - the goal is to draw the user's attention to the search results.
I would like to hear feedback from the implementation of this ...
Thank you.

If you don't see it in the search results, it's most likely inefficient.
The wave of testing emojis in titles and descriptions has long passed. It doesn't bring any result.
