  javascript:var i,j,w,t='',v=new Array('a','A', 'e','E','i','I','o','O','u','U'),s=new  Array ('grave','acute','uml','circ');for(i=0; i<10;i++){for(j=0;j<4;j++){w=v[i]+s[j];t+=  '&'+w+' is &'+'amp;'+w+';<br/>';}}void (document.body.innerHTML=t);  

To display ISO Latin characters:

1.	javascript:var i,j,w,t='', Start off the bookmarklet by initializing four variables .
2.	v=new Array('a','A','e','E','i','I', 'o','O','u','U'), Initialize an array, v , which contains all the vowels.
3.	s=new Array('grave','acute','uml', 'circ'); Here's another array, s , which contains all the diacritical character codes.
4.	for(i=0;i<10;i++){ This line sets up i to loop through the v array.
5.	for(j=0;j<4;j++){ And this line sets up j to loop through the s array.
6.	w=v[i]+s[j]; In this line, we set up the variable w to be the vowel concatenated with the code.
7.	t+='&'+w+' is &'+'amp;'+w+';<br />'; So the output is the character, followed by the HTML code required to display that character. All of these codes are preceded by an ampersand (&).
8.	}}void(document.body.innerHTML=t); And finally, the document gets displayed, as shown in Figure 17.17 . Figure 17.17. The result of this script is a new window with all the possible accented characters.
