There are some symbols missing on opensymbol. They are requiered for LO math improvment. The list is on her (on exception of some of them): https://en.wikipedia.org/wiki/Blackboard_bold Note: the really one important is: U+2119 for setp.
All alphabet letters in OpenSymbol characters are just recatngles, the same shape.

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.

Dante: would you like to close this as fixed? :)
