U+E004D "󠁍" Tag Latin Capital Letter M Unicode Character

U+E004D "󠁍" Tag Latin Capital Letter M is part of the Tags block, a specialized set of invisible formatting characters used for language tagging in plain text, where it functions as a control character within a sequence rather than a standalone letter. Designed for interoperability with older text encoding schemes, this character is rarely encountered in typical writing because it requires specific software support and is primarily employed to embed language metadata, such as marking a text segment as being in a particular language by combining it with other tag characters and a cancel tag.
