+ * Orders are generic to a language. So the codepoint with order X in
+ * CHARSET1 maps to the same character as the codepoint with the same
+ * order X in CHARSET2 for the same language.
+ * As such, it is possible to get missing order. For instance the

+Мрмот је дугачак отприлике педесет сантиметара, заједно с репом који сам износи двадесет сантиметара. Тежак је четири до пет килограма, ретко више. Има прекрасно крзно сивкасте боје, које на светлости добија златносмеђе преливе. Као мишеви, зечеви и остали глодари, мрмот има секутиће који непрестано расту па мора често нешто да глође да би их трошио. На предњим ногама има четири прста наоружана повијеним канџама помоћу којих животиња узима траву и гранчице, приноси храну устима и копа земљу. На задњим ногама има пет прстију с прилично кратким канџама. Мрмот има веома оштар вид, а уши му хватају сваки и најслабији звук.[2]
