U+E003F "󠀿" Tag Question Mark Unicode Character

Unicode Version 17.0

󠀿

U+E003F "󠀿" Tag Question Mark is a special purpose character belonging to the Tags block, which was originally intended for use in language tagging and other metadata within plain text. It does not represent a standard punctuation question mark, but instead serves as a visible tag component, part of a system that allowed combining multiple tag characters to encode language or script information without altering the visible appearance of the text in compliant systems. This character, like others in the Tags block, is typically invisible in modern user interfaces and is primarily of interest for historical or technical implementations of Unicode tagging.
