@Justin
To distract you from the color bullet stuff? Maybe something 'easy' (or maybe not, what the hell do I know). Looks like unsupported symbols.

This is not an OpenSymbol font issue. This is a filter issue (export to OOXML, and/or import from OOXML).

The original chemical formula in LO7 StarMath is:

   nitalic{NH_3 + H_2 O %Ux21CC  NH_4^{+{}} + OH^{`-{}} }

In LO7 on roundtrip to OOXML (Word 2007-365):

   {NH} rsub {3} + {H} rsub {2} O ⇌ {NH} rsub {4} rsup {+} + {OH} ^ {  −}

Or, in LO7 on roundtrip to MS Word 97-2003 binary:

    size 12{"NH" rSub { size 8{3} } +H rSub { size 8{2} } O⇌"NH" rSub { size 8{4} }  rSup { size 8{+{}} } +"OH" rSup { size 8{` - {}} } } {}


The OOXML filtering has the issue, and because the chemical formula is not rendered non-italic when opened in Word issue start with the ww8 export.

The sm error markers seem to be from the

rsup {+} + {OH} ^ {  −}

which will render correctly if notated:

rsup {"+"} + {OH} rsup {"−"};  or mixed rsup {"+"} + {OH} ^ {"−"}


Meaning that rather than explicitly literal with the quotes as now, the sm parser might need to allow/accept them as literals when bracketed alone in an rsub or rsup expression?

Those are chemistry formulas.
In the new parser I'm implementing there will be special namespace for formulas in which syntax is optimized for that. I'll take it into account.

Still presents in LO 7.6 Dev under Windows 10(x64).
