Things not supported by unicode-math:

• things that is not math, ignore
• circled digits: can search for "circled numerals" in symbols, but overall no specific control sequence I think
• stigma: LaTeX has \textstigma? some package has this symbol but stigma: $Ϛ$ Ϛ $ϛ$ ϛ does not work by default in unicode-math (character not in font)
• tried \setmathfont{DejaVu Math TeX Gyre} doesn't have either
• 〚 is non-math version of ⟦
• µ is non-math version of μ
• 〈 is deprecated version of ⟨
• ⇰ is... not sure? similar to Mapsto but not quite -- the whole block seems to be not available in math fonts https://en.wikipedia.org/wiki/Arrows_%28Unicode_block%29
