### C.4 German Sharp S

The German Sharp S or Eszett does not have an uppercase equivalent. Instead when ‘`ß`’ is converted to ‘`SS`’. The conversion of ‘`ß`’ to ‘`SS`’ requires a special rule, and increases the length of a word, thus disallowing inplace case conversion. Furthermore, my general rule of converting all words to lowercase before looking them up in the dictionary won’t work because the conversion of ‘`SS`’ to lowercase is ambiguous; it can be ‘`ss`’ or ‘`ß`’. I do plan on dealing with this eventually.
