Clicking a symbol copies a text character, not a picture. It pastes anywhere Unicode is accepted, takes on the surrounding text colour if it is a text character, and keeps its meaning because the character itself travels with the copy.
You are copying text
Each symbol tile contains a character. Copying puts that character on your clipboard the same way copying a word does. This is why it works in fields that accept no images, and why it can be searched, stored in a database and sent in a message.
Check the code point first
Every tile on this site shows a U+ value. Visually similar symbols are often separate characters — the multiplication sign and the cross mark, the bullet and the bullet operator, the copyright sign and the circled letter c. If the symbol is going anywhere it will be compared by software, the code point is what tells you which one you have.
Text symbols and emoji behave differently
A text symbol is drawn by your text font, inherits your text colour, and scales with your font size. An emoji is drawn by a separate colour font at a size it chooses and ignores CSS colour. Some characters can be either, depending on an invisible variation selector that follows them.
Expect rendering to vary
Unicode fixes which character a code point is, not how it looks. Stroke weight, proportions and alignment are font decisions, so the same symbol can look noticeably different across devices. A character with no glyph in the current font appears as an empty box — valid text, missing drawing.
Where symbols get rejected
Fields that restrict input — usernames, filenames, some form validation — may strip or refuse symbols, especially ones from supplementary planes. This is the app's decision. Test the exact field before relying on it, and keep essential information in plain words.
Symbols are decoration, not labels
A symbol on its own tells a screen reader only its character name. ⚠ announces as "warning sign" with no indication of what the warning is; ✓ in a table conveys nothing about what is true. Pair symbols with text wherever they carry meaning.
