@Deprecated
public class ArabicLetterTokenizer
extends LetterTokenizer

Deprecated.

(3.1) Use StandardTokenizer instead.

Tokenizer that breaks text into runs of letters and diacritics.

The problem with the standard Letter tokenizer is that it fails on diacritics. Handling similar to this is necessary for Indic Scripts, Hebrew, Thaana, etc.

You must specify the required Version compatibility when creating ArabicLetterTokenizer:

• As of 3.1, CharTokenizer uses an int based API to normalize and detect token characters. See isTokenChar(int) and CharTokenizer.normalize(int) for details.
