Unicode character Registered Sign
About this character
The character ® is known as Unicode character Registered Sign and carries the Unicode code point U+00AE, which is 174 in decimal. It belongs to the Latin-1 Supplement block (U+0080–U+00FF), which gathers the accented letters of Western European languages along with the punctuation and symbols inherited from ISO 8859-1.
In memory, ® takes 2 bytes in UTF-8 (0xC2 0xAE) and 1 in UTF-16 (0x00AE). 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+00AE, which is 174 in decimal and 0256 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+00AE. 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 %C2%AE. Modern filesystems accept it, though it is still risky when moving files between systems. For passwords, some forms reject non-ASCII characters outright.
