Simplified Chinese turns to Traditional Chinese when copy and pasted elsewhere
I've having trouble copy and pasting a simplified Chinese PDF. The text is automatically turned into traditional Chinese when pasted elsewhere.
I tried extracting it to Word, html... Still, it turns the whole document from simplified to traditional Chinese... How is that possible?
I checked the font that's embedded, and I can't recognize it. So, I'm guessing that's the issue?
I double checked another simplified Chinese document. The embedded font is recognizable, and i don't have this issue.

Is there a way to replace the embedded font or another way to fix this issue?
