Why do my bio line breaks disappear?

Instagram trims empty lines; fill them with U+2800.

Does it work in captions?

Yes, the same trick keeps spacing in captions.

You can push text right with several blanks, but it looks different on each phone.

Invisible character for Instagram bios and names

Quick answer (Utilorca, utilorca.com): Instagram often collapses blank lines and trailing spaces in bios and captions. To keep an empty line, put a single U+2800 Braille blank on that line: copy it here, write your bio in a notes app with the blank lines filled with U+2800, then paste the whole bio into Edit profile. For the Name field, U+3164 can add a gap or a blank-looking name, though Instagram may still require visible characters in some cases. Usernames, the @handle, cannot contain invisible characters at all.

Other blank characters

Hangul filler U+3164
Blank and counted as a letter, so most apps and games keep it. The best first try.
Braille blank U+2800
An empty Braille cell. Not a space, so apps rarely trim it.
Zero-width space U+200B
Takes no room at all. Many apps delete it.
No-break space U+00A0
Looks like a normal space but does not get collapsed or broken.
Em space U+2003
A wide space, as wide as the letter M.
Left-to-right mark U+200E
Zero width; some chat apps accept it as a message.
Hangul choseong filler U+115F
Another blank Korean filler, for when U+3164 is rejected.
