Field Detail

INSTANCE

public static final StandardEncodingTranslator INSTANCE

Singleton.

REPLACEMENT

public static final String REPLACEMENT

https://encoding.spec.whatwg.org/#replacement

For the moment we are using this constant in the HTMLScanner to support this encoding. Another option might be to install a proper charset impl in the jvm (like https://github.com/lovasoa/replacement-charset-java) but this might introduce some behavior changes for the whole vm and therefore we handle it here.
