LSSerializer docs have invalid character

The javadoc-generated file has an invalid character on line 236, in the sentence:

An example would be serializing
 the element &lt;LaCa\F1ada/&gt; with <code>encoding="us-ascii"</code>.

It shows up in the previous text as "\F1".

It arises from this text in the source file:
jaxp/src/java.xml/share/classes/org/w3c/dom/ls/LSSerializer.java

An example would be serializing
 * the element &lt;LaCa\u00f1ada/&gt; with <code>encoding="us-ascii"</code>.

javadoc should be better at handling characters like this (JDK-8183582) but it would also be better if the source used an entity here, instead of a direct Unicode character. Unicode f1 is "Latin Small Letter N with Tilde" so the appropriate entity is &ntilde;
