- * Default {@link ICUTokenizerConfig} that is generally applicable

- * Generally tokenizes Unicode text according to UAX#29 
- * ({@link BreakIterator#getWordInstance(ULocale) BreakIterator.getWordInstance(ULocale.ROOT)}), 
- * but with the following tailorings:
- * <ul>
- *   <li>Thai text is broken into words with a 
- *   {@link com.ibm.icu.text.DictionaryBasedBreakIterator}
- *   <li>Lao, Myanmar, and Khmer text is broken into syllables
- *   based on custom BreakIterator rules.
- *   <li>Hebrew text has custom tailorings to handle special cases
- *   involving punctuation.
