Instagram limits that matter
Your bio is capped at 150 characters and your name at 30. Styled letters from the Mathematical Alphanumeric block count as one character each in Instagramโs counter, but decorations like ๊งเผบ เผป๊ง add several.
The display name field accepts styled text and is searchable, but only by the characters you actually typed. If people search for โMayaโ, ๐๐ช๐๐ช will not match, so keep your plain name somewhere in the name field.
