--- Comment #5 from V Stuart Foote <vstuart.foote at utsa.edu> ---
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.
