Frequently asked questions
What is the Unicode code for ↡?
Its code point is U+21A1, which is 8609 in decimal and 020641 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+21A1. 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%86%A1. Modern filesystems accept it, though it is still risky when moving files between systems. For passwords, some forms reject non-ASCII characters outright.
