I tried to display angle symbol but when I run app only red rectangle is displayed. formulaControl.Formula = @"\oint_{S}\vec{E}d\vec{S}=\oint_{S}EdS*\angle (\vec{E},d\vec{S})=\oint_{S}EdScos, 0=\oint_{S}Eds=E\oint_{S}dS=ES";

Can you please fix that issue?

Are this two things below required? @FoggyFinder https://github.com/opencollab/jlatexmath/blob/c9a962cc7cbd2506d46c21eda93c1a4278b1c5ef/jlatexmath/src/main/resources/org/scilab/forge/jlatexmath/TeXFormulaSettings.xml#L605 https://github.com/opencollab/jlatexmath/blob/c9a962cc7cbd2506d46c21eda93c1a4278b1c5ef/jlatexmath/src/main/resources/org/scilab/forge/jlatexmath/TeXSymbols.xml#L185

Perhaps. Why can't you experiment with code in a bit and find it out?

@FoggyFinder I tried to copy that two lines and after building I tried to run WpfMath.Example and I got error: WpfMath.SymbolMappingNotFoundException: 'Cannot find mapping for the symbol with name 'angle'.'

@FoggyFinder Can you please help me to add \angle symbol?

I have skimmed through the fonts we're using and found no angle symbol there. Seems we'll need additional font for that.

Also I've checked the Computer Modern font sources, and haven't find the angle character there. Does it even exist?

jsMath uses msam10 and msbm10 fonts for it

@pavledev if necessary, there is a temporary solution in the form of using a similar command \text{∠} and font changes, for example from the suggested

Is there's any chance this will hopefully be fixed? I sadly lack the expertise to fix it myself.
