most unicode characters work, but a few will not work in obs

[Doksha]

Im trying to use text(GDI+) to display the currently playing song, but one of the artist's names (apparently the forum just removes it so I can actually paste it here) just shows up as boxed question marks in obs. I am using the same font notepad is using (notepad displays it just fine) but it still shows just question marks. Is there something I need to do to get these to show properly? I am using UTF-8 encoding, but I have also tried ANSI (is just turns the boxed ? to normal ? and also cannot read any other unicode characters) and Unicode, which just prints 2 rhombus question marks.
nearly all other unicode characters obs can read fine, just a select few (some of which I need)
FreeType2 just doubles the amount of boxed question marks

Same problem. Specifically characters in this set:



I think these are multi-byte characters if that matters…

The forum scrubbed the unicode chars

I will get a hex code representation, one sec…

Here are the UTF-8 code points for some of the characters that won't display:

 (U+1D5D4) [Bytes: F0 9D 97 94] #Looks like an A
 (U+1D5D8) [Bytes: F0 9D 97 98] #Looks like an E
 (U+1D5E2) [Bytes: F0 9D 97 A2] #Looks like an O
