The Wikipedia has the following information about this codepoint:

In the German alphabet, the letter ß, called "Eszett" (IPA: [ɛsˈtsɛt]) or "scharfes S", in English "sharp S", is a consonant that evolved as a ligature of "long s and z" (ſz) and "long s over round s" (ſs). When speaking it is pronounced [s] (see IPA). Since the German orthography reform of 1996, it is used only after long vowels and diphthongs, while ss is written after short vowels. The name eszett comes from the two letters S and Z as they are pronounced in German. In German, it is also called scharfes S (IPA: [ˈʃaɐ̯.fəs ˈʔɛs, ˈʃaː.fəs ˈʔɛs], meaning "sharp S". Its Unicode encoding is U+00DF.

While the letter "ß" has been used in other languages, it is now only used in German. However, it is not used in Switzerland, Liechtenstein or Namibia. German speakers in Germany, Austria, Belgium, Denmark, Luxembourg and South Tyrol, Italy follow the standard rules for ß.
