I’ve been trying to add the oplus symbol to my formulas and I’m only getting the red question mark indicating the symbol is missing from the font. Normally the fix I’d try is to swap to a different font, but in the Formula editor only one Liberation font is available to select for each font choice. In contrast, for regular text in Writer and Impress all the installed fonts are available.
I’ve tried the Formula editor in both Writer and Impress and in LibreOffice 5.2 & 5.3 and I’ve had no success in fixing the problem. I’d like help either fixing the Liberation Serif font so that it doesn’t have missing formula symbols and/or help in getting the formula editor to recognize more fonts.
