U+001C "FS" FILE SEPARATOR Unicode Character
Unicode Version 17.0
FS
U+001C "FS" FILE SEPARATOR is a control character originally defined in the ASCII standard as a communication and data structuring tool, serving to separate distinct logical units or files within a larger data stream or document. It is one of a set of four "information separators" that also includes the GS (Group Separator), RS (Record Separator), and US (Unit Separator), arranged hierarchically from largest to smallest division. While its use has largely been replaced by modern file system and database structures, it persists in legacy data formats, telecommunications protocols, and certain specialized text processing contexts where explicit delimiters are needed to organize information without relying on higher-level metadata.
