Janine Wissler: Tweet from 25 February 2018, 14:34. In: Twitter. 25 February 2018, accessed on 15 October 2020: “In the identity card, there is a ß in the name field and a double S at the bottom, because there was no capital ß. In times of internet and e-mail it is difficult to have a ß in a name and I use the double S notation so that it is consistent with the website and e-mail."
