How do I use this symbols keyboard?
Click or tap a symbol to add it to the text box, type anything else on your own keyboard as usual, then press Copy to copy your text and paste it anywhere: a message, a document or a social media post.
Why does a symbol show as a box?
The symbols are standard Unicode characters, so they work anywhere text does, but each device draws them with its own fonts. If the place you paste into shows a box or a question mark, its font has no picture for that symbol, and it may show correctly on another device.
