  <!-- When we encounter a character that the current font doesn't
       support, gfx::GetFallbackFontForChar() returns the first font
       that does have a glyph for the character. The list of fonts is
       sorted by a pattern that includes the current locale, but doesn't
       include a font family (which means that the fallback font depends
       on the locale but not on the current font).

       DejaVu Sans is commonly the only font that supports some
       characters, such as "⇧", and even when other candidates are
       available, DejaVu Sans is commonly first among them, because of
       the way Fontconfig is ordinarily configured. For example, the
       configuration in the Fonconfig source lists DejaVu Sans under the
       sans-serif generic family, and appends sans-serif to patterns
       that don't already include a generic family (such as the pattern
       in gfx::GetFallbackFontForChar()).

       To get the same fallback font in the layout tests, we could
       duplicate this configuration here, or more directly, simply
       append DejaVu Sans to all patterns. -->
