Is there a font in Mathematica that corresponds to $$\Re$$ I found \[DoubleStruckCapitalR] corresponds to 
But this is different to the R I have written in first.
I think SWGothg is as close as I can get with fonts I have installed.
Style["R", FontSize -> 12, FontFamily -> "SWGothg"]
\[GothicCapitalR]; also see\[ScriptCapitalR]. Character codes are 8476 and 8475 respectively. – Syed Aug 25 '21 at 03:51Text[Style[R, 24, FontFamily -> #]] & /@ $FontFamiliesto see all the fonts. Yep: https://www.johndcook.com/blog/2018/07/21/fraktur-math/ – David G. Stork Aug 25 '21 at 05:05FromCharacterCode[120189]. Either something will show up in the output cell or not. Still go ahead and copy/paste the invisible output into MS word. Of course inside MS word, just type U1D57D and then press Alt-X to see if you like the font. Word has proper support for unicode chars > 65535. For a more detailed Q/A: https://stackoverflow.com/questions/5597013/reading-an-utf-8-encoded-text-file-in-mathematica. The unicode page for unicode equivalents of Fraktur is : https://www.w3.org/TR/MathML2/1D5.html. I am out of ideas now. – Syed Aug 25 '21 at 07:25Style["R", FontSize -> 46, FontFamily -> "Euclid Fraktur"]? – kglr Aug 25 '21 at 09:41{Text[Style[R, 24, FontFamily -> #]], #} & /@ $FontFamiliesso I could see what's what. "SWGothg" looks very close:Style["R", FontSize -> 46, FontFamily -> "SWGothg"]– Rudy Potter Aug 31 '21 at 17:40
