The VideoLAN Forums

I read that on the Window you can:
1. Open Preferences and enable the Advanced mode (lower left).
2. Video > Subtitles/OSD > Text renderer | Font : /System/Library/Fonts/AppleGothic.dfont
3. Input/Codecs | Subtitles track : 0 (don't confuse with Subtitles track ID)
4. Input/Codecs > Other Codecs > Subtitles | Subtitles text encoding : EUC-KR

But in Mac, we have different menu.
Is there anyway we can play smi file on Mac version?

Those steps are precisely for OSX:

How to get korean or other region subtitles working with VLC. The problem is because Unicode fonts on Windows are not installed by default, however on mac they are.
These steps works with both Windows 10 and macOS (OSX):

Go to VLC -> Preferences -> Subtitles/OSD.

1) Set default encoding to "Korean (EUC-KR/CP949)
2) Set font to "Arial Unicode MS"

In Windows 10 you have to install then manually, the fonts are copyrighted. Microsoft Office and other software install them depending on the program and version. On OSX they in "/Library/Fonts/Arial Unicode.ttf"

Additionally, you can leave the default encoding to your local or default setting and convert the SMI file to UTF-8-BOM with Notepad++ for example.
