I had a project head tell me I had to leave the registered trademark symbol ® in standard, unbolded, non-italicized Myriad Pro.
Is this a requirement or just a style choice? Curious to get feedback before I engage further in the discussion with him.
My proofreader always had us un-format any register marks, trademarks, service marks, etc. It had to be in the same font as the copy, and superscripted.
I think this was because italicized, bolded ™s and ®s were harder to read, and the superscript made them smaller still. So you want a balance of emphasis (visible, but not dominant) and you want to retain readability, since they are legally important.
I wouldn’t change the font, but I would strip formatting.
