How to get word boundaries "character classes"?

[banbanpeppa]

Hi, Bryan:

Can you tell me how or where did you get this word boundaries "character classes" shown below? Since now this boundaries you given won't work well with the Unicode Text Segment develops.

elasticsearch-analysis-standardext/src/main/java/org/apache/lucene/analysis/standard/ExtensibleStandardTokenizerImpl.java

Lines 69 to 81 in cc63b2a

	/**
	* Word Boundary "character classes" that are used in the ZZ_CMAP_PACKED
	* string
	*/
	public static final Character WB_CLASS_BREAK = '\0';
	public static final Character WB_CLASS_LETTER = '\176';
	public static final Character WB_CLASS_NUMERIC = '\200';
	public static final Character WB_CLASS_MID_LETTER = '\202';
	public static final Character WB_CLASS_MID_NUMBER = '\203';
	public static final Character WB_CLASS_MID_NUMBER_LETTER = '\204';
	public static final Character WB_CLASS_EXTENDED_NUM_LETTER = '\205';
	public static final Character WB_CLASS_SINGLE_QUOTE = '\212';
	public static final Character WB_CLASS_DOUBLE_QUOTE = '\213';

Thanks for your help!😄
