[LE] How to add support of not standart symbols to papyrus: SetDisplayName?

[myav]

How to increase standart supported list of the symbols, that to see new symbols instead to squares ?

 

I want to add 3 symbols to function: SetDisplayName

 

star: unicode U+272D

skull with bones: unicode U+2620

skull without bones: unicode U+1F480

 

I know, that this is possible, because i saw mod: SKSE Russian Helper, which allows to use Cyrillic "windows-1251" in the function SetDisplayName without squares.

But, that mod is dll file, so i can't check source that to repeat method and to add my custom symbols too

 

Can someone help and tell how to do it?
