Frequently asked questions
What is the Unicode code for ▧?
Its code point is U+25A7, which is 9639 in decimal and 022647 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+25A7. 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%96%A7. Modern filesystems accept it, though it is still risky when moving files between systems. For passwords, some forms reject non-ASCII characters outright.
