Latest version of PMS doesn't support subtitle Korean

Server Version#: 1.15.1 latest beta version
Player Version#: Android application, LG tv application (all up-to-date versions)

Hi, I found a problem as soon as I updated my PMS from 1.14 to 1.15 latest beta version. All devices that I’m using can’t play videos with external .srt(Korean) properly. Video was fine, but subtitle was not.

Of course, my all Korean subtitles are incoded in UTF-8 and those were played well in previous official version of PMS. So, I had to go back to 1.14 version of PMS.

I’m wondering if there are any plans to solve this problem?
