NormalizersUtil.java

	/**
	 * Normalizes a {@link CharSequence} using the {@link Normalizer.Form#NFKC} method;
	 * It is a Unicode normalization form that replaces characters with their
	 * compatibility equivalents and then applies canonical composition.
	 * This method is useful for ensuring that strings containing different
	 * representations of the same characters are treated as equal.
	 * <p>
	 * Example 1:
	 * Input: "№１２３"
	 * Output: "No123"
	 * <p>
	 * Example 2:
	 * Input: "Ｈｅｌｌｏ Ｗｏｒｌｄ"
	 * Output: "Hello World"
	 *
	 * @param cs the input string to be normalized
	 * @return the normalized string
