About this character
The character □ is known as Shape White Square and carries the Unicode code point U+25A1, which is 9633 in decimal. It belongs to the Geometric Shapes block (U+25A0–U+25FF), which gathers squares, circles, triangles and diamonds used as bullets, markers or diagram elements.
In memory, □ takes 3 bytes in UTF-8 (0xE2 0x96 0xA1) and 1 in UTF-16 (0x25A1). 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+25A1, which is 9633 in decimal and 022641 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+25A1. 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%A1. Modern filesystems accept it, though it is still risky when moving files between systems. For passwords, some forms reject non-ASCII characters outright.
