Emoji Rat
About this character
The character ๐ is known as Emoji Rat and carries the Unicode code point U+1F400, which is 128000 in decimal. It belongs to the Miscellaneous Symbols and Pictographs block (U+1F300โU+1F5FF), which gathers most of the emoji for objects, animals, food, weather and places.
In memory, ๐ takes 4 bytes in UTF-8 (0xF0 0x9F 0x90 0x80) and 2 in UTF-16 (0xD83D 0xDC00). That difference is why badly configured forms or databases garble this character: they assume one byte per character.

Frequently asked questions
What is the Unicode code for ๐?
Its code point is U+1F400, which is 128000 in decimal and 0372000 in octal. In HTML you can write it as 🐀 or 🐀.
Why does ๐ show up as a box or a question mark?
An empty box means the font has no glyph for U+1F400. The character is still in the text: switching to a font that covers the block (Noto, DejaVu or Segoe UI Symbol) makes it appear.
Can I use ๐ in a filename, a URL or a password?
In a URL it must be encoded as %F0%9F%90%80. Modern filesystems accept it, though it is still risky when moving files between systems. For passwords, some forms reject non-ASCII characters outright.
