setDefaultCharacterEncoding

open fun setDefaultCharacterEncoding(@Nullable defaultCharacterEncoding: @Nullable String)(source)

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().
