General Category - Unassigned

Unassigned is a special value used to mark code points that have not yet been allocated any specific character meaning within the standard. These positions are reserved for future use, allowing new scripts or symbols to be added without breaking existing text. They are not invisible glyphs; instead, they indicate that no character has been officially defined there yet. This value helps software distinguish between known characters and those that are simply placeholders, avoiding misinterpretation of raw binary data as meaningful written text. Practically, it means a renderer will not try to guess a shape or function for that code point, and it enables consistent handling of undefined ranges across different systems and versions of the standard.
