v 5.0.4 still present
Actually if one looks at the OOXML they are capital letters marked up with a "DoubleStruck" style. LibreOffice Formula editor does not parse the MS Formula that is bug 101411 However, with introduction of Unicode support it is trivial to insert symbols beyond the currently defined set in StarMath markup (each with glyph coverage in OpenSymbol), i.e. emptyset -- U+2205 (EMPTY SET) aleph -- U+2135 (ALEF SYMBOL) setN -- U+2115 (DOUBLE-STRUCK CAPITAL N) setZ -- U+2124 (DOUBLE-STRUCK CAPITAL Z) setQ -- U+211A (DOUBLE-STRUCK CAPITAL Q) setR -- U+211D (DOUBLE-STRUCK CAPITAL R) setC -- U+2102 (DOUBLE-STRUCK CAPITAL C) and a limited set of Special characters. and the StarMath markup for the formula here (default rendered into OpenSymbol) is "plusminus setN" *** This bug has been marked as a duplicate of bug 101411 ***
