U+E005B "󠁛" Tag Left Square Bracket Unicode Character

U+E005B "󠁛" Tag Left Square Bracket is part of the Tags block, a special collection of code points designed for use in language tagging and text processing rather than for visible display. It belongs to a deprecated mechanism intended to embed metadata within plain text, such as indicating a specific language or script via tags formed from these characters, but it was never widely implemented and is now considered obsolete for most purposes. As a result, this character typically appears as a invisible or placeholder glyph in standard fonts and is not meant for direct use in everyday writing or formatting.
