Method

Stringnormalize(String name)
normalize 
return normalize(name, -1);
Stringnormalize(String s)
Replaces all the funky characters with normal ASCII 
return Normalizer.normalize(s, Normalizer.Form.NFD).replaceAll("[^\\p{ASCII}]", "");
Stringnormalize(String s)
java.text.Normalizer is only available for jdk 1.6. 
return s;
Stringnormalize(String s)
Normalizes a string by removing features that should not be considered as differentiating between two strings (such as accents and case). 
s = Normalizer.normalize(s, Normalizer.Form.NFD);
s = s.replaceAll("\\p{InCombiningDiacriticalMarks}+", "");
s = s.toLowerCase();

s = s.replaceAll("([a-z])([0-9])", "$1 $2");
s = s.replaceAll("([0-9])([a-z])", "$1 $2");
return s;
Stringnormalize(String s)
normalize
