Is there a way to get rid of accents and convert a whole string to regular letters?

Is there a better way for getting rid of accents and making those letters regular apart from using

method and replacing letters one by one?



It doesn't need to include all letters with accents like the Russian alphabet or the Chinese one.

Use java.text.Normalizer to handle this for you.

string = Normalizer.normalize(string, Normalizer.Form.NFD);

This will separate all of the accent marks from the characters. Then, you just need to compare each character against being a letter and throw out the ones that aren't.

string = string.replaceAll("[^\\p{ASCII}]", "");

If your text is in unicode, you should use this instead:

string = string.replaceAll("\\p{M}", "");

For unicode, \\P{M} matches the base glyph and \\p{M} (lowercase) matches each accent.

Thanks to GarretWilson for the pointer and for the great unicode guide.
