Glyph for U+00AE

U+00AE Registered Sign

U+00AE was added in Unicode version 1.1 in 1993. It belongs to the block U+0080 to U+00FF Latin-1 Supplement in the U+0000 to U+FFFF Basic Multilingual Plane.

This character is a Other Symbol and is commonly used, that is, in no specific script. The character is also known as registered trade mark sign (1.0).

The glyph is not a composition. Its width in East Asian texts is determined by its context. It can be displayed wide or narrow. In bidirectional text it acts as Other Neutral. When changing direction it is not mirrored. The word that U+00AE forms with similar adjacent characters prevents a line break inside it. The glyph can be confused with one other glyph.

The CLDR project calls this character “registered” for use in screen reading software. It assigns these additional labels, e.g. for search in emoji pickers: R.

This character is designated as an emoji. It will be rendered as monochrome character on conforming platforms. To enable colorful emoji display, you can combine it with Glyph for U+FE0F Variation Selector-16: ®️ See the Emojipedia for more details on this character’s emoji properties.

The Wikipedia has the following information about this codepoint:

The registered trademark symbol, ®, is a typographic symbol that provides notice that the preceding word or symbol is a trademark or service mark that has been registered with a national trademark office. A trademark is a symbol, word, or words legally registered or established by use as representing a company, product or service.

Unregistered trademarks can instead be marked with the trademark symbol, , while unregistered service marks are marked with the service mark symbol, . The proper manner to display these symbols is immediately following the mark; the symbol is commonly in superscript style, but that is not legally required. In many jurisdictions, only registered trademarks confer easily defended legal rights.

In the US, the registered trademark symbol was originally introduced in the Trademark Act of 1946.

Because the ® symbol is not commonly available on typewriters (or ASCII), it was common to approximate it with the characters (R) (or (r)). An example of a legal equivalent is the phrase Registered, U.S. Patent and Trademark Office, which may be abbreviated to Reg U.S. Pat & TM Off. in the US.
