Invisible text in your Instagram bio
The most popular use of invisible characters on Instagram is creating blank lines in your bio. Instagram doesn't allow empty lines natively, but invisible characters bypass this limitation.
The Zero-Width Space (U+200B) is the best choice for bio spacing — paste one on each line you want blank. For wider visual gaps, try the Braille Blank (U+2800), which occupies a full character width while showing nothing.
You can also use the Hangul Filler (U+3164) to create a display name that appears completely blank, giving your profile a minimalist or mysterious aesthetic.
