abstract fun setDefaultCharacterEncoding(defaultCharacterEncoding: String): Unit
Sets the default character encoding to use. Note: Many JVM implementations support the setting of this attribute via system property on startup (namely, the file.encoding property). For JVMs where this is the case, setting the file.encoding property via #setSystemProperties(java.util.Map) or similar will have no effect as this value will be overridden by the value specified by #getDefaultCharacterEncoding().
defaultCharacterEncoding - The default character encoding. Use null to use this JVM's default charset
