Upwards Paired Arrows
About this character
The character ⇈ carries the official Unicode name “Upwards Paired Arrows” and the code point U+21C8, which is 8648 in decimal. It belongs to the Arrows block (U+2190–U+21FF), which gathers single, double and curved arrows used in typography, mathematics and user interfaces.
In memory, ⇈ takes 3 bytes in UTF-8 (0xE2 0x87 0x88) and 1 in UTF-16 (0x21C8). 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 ⇈?
Its code point is U+21C8, which is 8648 in decimal and 020710 in octal. In HTML you can write it as ⇈ or ⇈.
Why does ⇈ show up as a box or a question mark?
An empty box means the font has no glyph for U+21C8. 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 ⇈ in a filename, a URL or a password?
In a URL it must be encoded as %E2%87%88. Modern filesystems accept it, though it is still risky when moving files between systems. For passwords, some forms reject non-ASCII characters outright.
