325N/A/**
325N/A * {@link Writer} that escapes characters that are unsafe
325N/A * as Javadoc comments.
325N/A *
325N/A * Such characters include '<' and '&'.
325N/A *
325N/A * <p>
325N/A * Note that this class doesn't escape other Unicode characters
325N/A * that are typically unsafe. For example, &#x611B; (A kanji
325N/A * that means "love") can be considered as unsafe because
325N/A * javac with English Windows cannot accept this character in the
325N/A * source code.
325N/A *
325N/A * <p>
325N/A * If the application needs to escape such characters as well, then
325N/A * they are on their own.
