Method Details

canonicalCaseFold

public static String canonicalCaseFold(String string)

Applies Unicode Canonical Case Fold Normalization as defined in https://www.w3.org/TR/charmod-norm/#CanonicalFoldNormalizationStep This applies, in sequence: - canonical decomposition (NFD) - case folding Note that the result is **not** recomposed (NFC), i.e. the optional post-folding NFC normalization is not applied. In other words, the result is suitable for string comparison for case-insensitive string comparison, but not for display.

Parameters:

string - the string to normalize

Returns:

the string normalized by applying NFD then case folding
