"Capital sharp s (ẞ) [...] never occurs word-initially in German text, and traditional German printing (which used blackletter) never used all-caps. When using all-caps, current spelling rules require the replacement of ß with SS.[1] However, in 2010 the use of the capital sharp s became mandatory in official documentation when writing geographical names in all-caps."
