Other Door like No. 5

Some doors have Nº or something like it on it I tried to draw it here:

and got this ⍛ or something like but I want this N⍛ 5 on the door WITH THE CORRECT unicode so how do I do this?

 

Here, have a Wikipedia link.

 

That sign doesn't look like that on the picture it looks like an normal N with a o it doesn't have hooks.

 

Use #
That is what gives it that special look. The font's # sign looks like the number sign.

 

Is this wanted like this?

 

Okay. It's done like this.
№ is called the numero symbol. It is one single character, and will look fancy as you wish, as it changes based on font. Not an N and then an ⍛, just the single character, shown above. This can be seen in the following fonts:

Copy this symbol:

Code:

№

And it should look alright.
