+Fontconfig fonts.conf for a Bitstream Vera default
+
+https://github.com/eosrei/emojione-color-font
+
+The DejaVu font family is based on the Bitstream Vera font family to provide
+greater unicode coverage. The only way to override the emoji it includes is
+to make the emoji font the primary system font. This shouldn't be a problem,
+but a number of programs do not correctly use font fallback resulting in font
+rendering errors everywhere.
+
+This font.conf makes Bitstream Vera the default font for Serif, Sans-Serif,
+and Monospace font requests since it does not contain any Unicode Emoji
+characters. Emoji One Color font is the first fallback, followed by DejaVu
+to provide everything else.
+
+Install required fonts with:
+sudo apt-get install ttf-bitstream-vera
+
+Test with:
+fc-match -s serif
+fc-match -s sans-serif
+fc-match -s monospace
