Google Ad Copy

Just a quick question.
Do certain special characters such as » or ® make any difference in relations to writing Google ads, for example, improve rank or quality score?
The reason I ask is one my colleagues advised me to use them when i write new ads, and as I am fairly new to PPC I am unsure of the benefits if any, and I am unable to find information in regards to this on Google search.
Thanks in advance.
