Replace uml

REPLACE_UML

Type Function	STRING
Input STR	STRING (String input)
Output	STRING (String output)
	REPLACE_UML replaces umlauts with a combination of two characters so that the result contains no more umlauts. The large and small letters are considered here. If a word is all upper case and is an umlaut is mentioned, this is replaced by a capital letter followed by a lowercase letter, in the case of a ß which has no capitals there will always be replaced with two small letters. If the function REPLACE_UML is used on a uppercase word, then it must be ensured using the function UPPERCASE() that all capital letters that the lower case are again converted to uppercase.
	Ä > Ae, Ö > Oe, Ü > Ue, ä > ae, ö > oe, ü > oe, ß > ss.
