The Unicode glossary is useful for people doing documents, specifications, and general-purpose articles. Each of the glossary entries now has a link on it, and clicking on that link exposes it in the address bar of your browser. This makes it easy to add links directly to the Unicode glossary for terms that may be unfamiliar to readers, such as

http://unicode.org/glossary/#grapheme_cluster or
