Purpose: collect code or links that apply to specific aspects of German language or culture
If you need the umlauted and other special characters used in German, here they are:
� \u00C4 � \u00D6 � \u00DC � \u00E4 � \u00F6 � \u00FC � \u00DF
Also note that "�" (historically a ligature of "long-s" and "round-s") is an anomaly in case conversion - [string toupper �] should result in the two characters SS, but in the other direction it is not decidable whether [string tolower SS] should result in "ss" or "�". (RS)
