+setdigraph({chars}, {digraph})		*setdigraph()* *E1205*
+		Add digraph {chars} to the list.  {chars} must be a string
+		with two characters.  {digraph} is a string with one utf-8
+		encoded character. Be careful, composing characters are NOT
+		ignored.  This function is similar to |:digraphs| command, but
+		useful to add digraphs start with a white space.
+
+		The function result is v:true if |digraph| is registered.  If
+		this fails an error message is given and v:false is returned.
+
+		If you want to define multiple digraphs at once, you can use
+		|setdigraphlist()|.

+
+setdigraphlist({digraphlist})			*setdigraphlist()*
+		Similar to |setdigraph()| but this function can add multiple
+		digraphs at once.  {digraphlist} is a list composed of lists,
+		where each list contains two strings with {chars} and
+		{digraph} as in |setdigraph()|.
+		Example: >
+		    call setdigraphlist([['aa', 'あ'], ['ii', 'い']])
+<
+		It is similar to the following: >
+		    for [chars, digraph] in [['aa', 'あ'], ['ii', 'い']]
+			  call setdigraph(chars, digraph)
+		    endfor
+<		Except that the function returns after the first error,
+		following digraphs will not be added.
