According to spec: > If a given character is a Private-Use Area Unicode codepoint, user agents must only match font families named in the font-family list that are not generic families. If none of the families named in the font-family list contain a glyph for that codepoint, user agents must display some form of missing glyph symbol for that character rather than attempting installed font fallback for that codepoint. (https://drafts.csswg.org/css-fonts-4/#char-handling-issues) We are currently not ignoring generic font families for font fallback when a code point is in the private-use area (PUA).
