-/**
- * A TokenFilter that applies search term folding to Unicode text,
- * applying foldings from UTR#30 Character Foldings.
- * <p>
- * This filter applies the following foldings from the report to unicode text:
- * <ul>
- * <li>Accent removal
- * <li>Case folding
- * <li>Canonical duplicates folding
- * <li>Dashes folding
- * <li>Diacritic removal (including stroke, hook, descender)
- * <li>Greek letterforms folding
- * <li>Han Radical folding
- * <li>Hebrew Alternates folding
- * <li>Jamo folding
- * <li>Letterforms folding
- * <li>Math symbol folding
- * <li>Multigraph Expansions: All
- * <li>Native digit folding
- * <li>No-break folding
- * <li>Overline folding
- * <li>Positional forms folding
- * <li>Small forms folding
- * <li>Space folding
- * <li>Spacing Accents folding
- * <li>Subscript folding
- * <li>Superscript folding
- * <li>Suzhou Numeral folding
- * <li>Symbol folding
- * <li>Underline folding
- * <li>Vertical forms folding
- * <li>Width folding
- * </ul>
- * <p>
- * Additionally, Default Ignorables are removed, and text is normalized to NFKC.
- * All foldings, case folding, and normalization mappings are applied recursively
- * to ensure a fully folded and normalized result.
