From Martin Desruisseaux on javadoc-dev:
Hello

I noticed a behavioural change of {@code} inline tag with Java 10. In Java versions 5 to 8, text inside {@code} was rendered literally, including Unicode characters outside ASCII range. But in Java 10, Unicode characters are replaced by the "\u" escape sequence. For example:

    {@code foo(…)}

Was rendered as foo(…) in HTML javadoc generated by Java 8, but is now rendered as foo(\u2026) in javadoc generated by Java 10. Is this behavioural change intentional? I do not see notice about handling of Unicode characters in [1].
