White Cross Mark at U+1FBCB is a printable symbol from the Symbols for Legacy Computing block that represents a light, unfilled cross-shaped mark. It belongs to a group of characters encoded to preserve the graphic repertoires of older terminals, teletext systems, and character-cell computers rather than to serve as ordinary punctuation. Its most relevant use is in retrocomputing, emulator displays, and archival conversion of legacy text screens where a cross-shaped cell graphic must be recorded as text. In reconstructed terminal art, bulletin-board screens, or old computer game interfaces, it can function as a simple marker, cursor-like symbol, map tile, or UI decoration when that exact light cross was part of the original character set. It may also appear in Unicode-based recreations of boxy mosaic art, block graphics, and text-mode diagrams, especially when preserving one-cell symbols matters more than substituting a modern plus sign or multiplication sign. Font support is still uneven compared with mainstream symbols, so unsupported environments may show a missing-glyph box instead of the intended legacy-computing mark.
