Problem description: 
Math doesn't have support of double letters. They mean set of numbers. Well it has it, but symbols are written wrongly, in mathematics literature they are as Word shows.
So there are two bugs:
1 Incorrect set symbol
2 No support of Word set symbol
Operating System: All
Version: 4.3.5.1 rc

Everybody doesn't have a tool to "unrar".

On pc Debian x86-64 with master sources updated today, I could reproduce this.

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"
