Ⓜ️ is an emoji with a capital letter "M" surrounded by a circle. It can usually be used to represent things related to the letter "M", such as the logos of brands, places, names, etc. starting with "M". In some cases, it may also be a specific symbol of a particular organization, institution or product.
I went to a place marked with Ⓜ️ today.
There is an Ⓜ️ mark on this document.
