WebGL Arial does not display EUR sign (€)

Hello,
I found out that the EUR sign, €, does not display when using Arial font on WebGL.
Is there a way to fix this? Maybe they would show up by updating the Arial version that WebGL builds uses?

WebgGL builds don’t have access to system fonts and the included font is a kind of stripped down font without bold or special characters. You should include your own font in the project to fix this.
