The java.text.Collator class specification gives the following,

 * The following shows how both case and accents could be ignored for
 * US English.
 * {@snippet lang=java :
 * // Get the Collator for US English and set its strength to PRIMARY
 * Collator usCollator = Collator.getInstance(Locale.US);
 * usCollator.setStrength(Collator.PRIMARY);
 * if (usCollator.compare("abc", "ABC") == 0) {
 * System.out.println("Strings are equivalent");
 * }
 * }

That is, the wording implies the example will ignore case and accents. In reality, it only ignores case. We should update the example to reflect the wording.
