when slug generation method is on encoded, the mini oneboxing preview is not shown correctly:
This is a topic with encoded slug generation, تربیت گذشته و حال من درباره غذای باقیمونده در سفره - ایستگاه پرسش - پادپُرس
this is the same topic after I changed the slug generation to ascii: https://padpors.com/t/topic/2514
should it be like this? as one may think it is not working.
