The German language makes use of the letter ß, ligature which is a ligature of the letter "z" ans "s" in cursive scripts. It sound used for certain occurrences of the ''voiceless alveolar fricatives'', the sound of the "S" in the English word "sea", to avoid confusion with  the ''voiced alveolar fricative'', the sound of "z" in the English word "zoo", for which German commonly uses the letter "s".  The common name for this ligature is the ''Eszett''. The other most common special characters are the three vowels with [[Umlaut]], ''ä'', ''ö'' and ''ü''.

However, if the letter is not available it has to be replaced by the letters "ss", and not by "sz". In Switzerland and Liechtenstein this letter is generally omitted and "ss" will be used instead.
