That is not incorrect.

That simply means the font does not "cover" those Unicode glyphs.  Any font
chart program, or even LibreOffice's own Special Character dialog will show the
actual coverage of the font.

For its use as source for glyph symbols for formulas, bullets, reference marks
it is probably not necessary to have full coverage of Latin or Cyrillic blocks.
 But coverage of the Greek & Coptic Unicode blocks should probably be filled
out.

Also, providing full set of glyphs for these Unicode blocks would make sense: 

Superscripts and Subscripts -- U+2070–U+209F

Currency -- U+20a0-U+20cf

Letterlike Symbols -- U+2100–U+214F

Number Forms -- U+2150–U+218F

Miscellaneous Technical -- U+2300–U+23FF

Miscellaneous Symbols -- U+2600–U+26FF

Mathematical Alphanumeric Symbols -- U+1D400–U+1D7FF

Miscellaneous Symbols and Pictographs -- U+1F300–U+1F5FF

Emoticons -- U+1F600–U+1F64F

Supplemental Symbols and Pictographs -- U+1F900–U+1F9FF

Those with some mix of Combining diacritics, and Arrow blocks to round out the
OpenSymbol font and reducing or removing its PUA glyphs.
