Is there a way to make Kodi v16.1 display correctly Vietnamese subtitle fil?

Greetings:

I have a media player box Kdlinks A400 running Android 5 with pre-installed Kodi v16.1. When playing movies with Vietnamese subtitle srt file, Kodi replaces characters as boxes and my subtitle setting is as shown in the link below.

Note: I edit the picture to show the correct Vietnamese subtitle in the second line.

Incorrect Subtitle and Subtitle settings pictures

Already try the following without success:

– Installed Vietnamese language package per Kodi-Wiki how to instruction.
– Re-encoded srt file to either UTF-8 or Unicode.

Is there a way to make Kodi display correctly Vietnamese subtitle srt files?

Your time and help is greatly appreciated.
