+ * A {@link CharSequenceNormalizer} implementation that normalizes text in
terms of numbers:
+ * every maximal run of ASCII digits ({@code 0} to {@code 9}), that is the
longest unbroken
+ * stretch of consecutive digits, is replaced by a single space. For example,
{@code "a1234b56"}
+ * becomes {@code "a b "}. Non-ASCII digits, for example Arabic-Indic or
fullwidth digits, are
+ * not treated as digits and are left unchanged.
