The use of Superscript (such as ® or ™) in the account name of Windows

I'm looking for confirmation on whether Windows tenant or account names allow the use of Superscript or Subscript. Is it good practice even if it is copied and pasted, basically forced, in the account tenant and/or account name? Could this result in integration difficulties with third-party software and hardware or impact RAM or drivers?
Any insight will be greatly appreciated.

Here's an indirect answer about Azure tenant names (because O365 is based on Azure domains, or personal MS Accounts):
"Invalid user name" when you try to create a user name that contains a special character in Microsoft 365

If my memory is correct, MS Account bans special characters (except for @ when you're using an e-mail address as your identity).

Thank you, Garlin. I believe you are right. If anyone could join in, or any additional info you are aware of Garlin, who has experience of working with a PC that is set up this way and provide their experience of the long-term implications. Please add your thoughts.
I have come across Azure Engineers (yes, Azure Engineers) and "Experienced" technicians who are unaware of this little quirk, really basic Coding knowledge. Let's please set the record straight! The scarcity of this information could greatly benefit those seeking to avoid its consequences.
My follow-up question would be, if you come across a PC with this problem, what is the fix?

No.
You would find problems processing such characters in Terminal [particularly its Command prompt, which is ancient].


All the best,

Comment: the prohibition of using some characters in the OS goes back a long ways, started learning it with MS-DOS in late '80s when taking courses for work.
