Description
The example below will consider FontAwesome, but the problem seems to happen with other fonts too. The bug results in absent glyphs as detected by QFontMetrics::inFont() and no rendering for most of the glyphs from the FontAwesome font.
Test snippet:
// CODEPOINT_OF_AWESOME_AMAZON='f270' // CODEPOINT_OF_AWESOME_HOME='f015' // CODEPOINT_OF_AWESOME_AT='f1fa' QString unicodeTest = QString::fromUtf8(u8"\uf270\uf015\uf1fa"); QFont font(QLatin1String("FontAwesome"), 9, QFont::Normal); std::cerr << std::boolalpha; for (QChar c: unicodeTest) { std::cerr << " in font: " << QFontMetrics(font).inFont(c) << std::endl; }
With the following fontconfig configuration:
$ fc-list | grep -i "FontAwesome" /usr/share/fonts/awesome-terminal-fonts/fontawesome-regular.ttf: FontAwesome:style=Regular /usr/share/texmf-dist/fonts/type1/public/fontawesome/FontAwesome.pfb: FontAwesome:style=Regular /usr/share/texmf-dist/fonts/opentype/public/fontawesome/FontAwesome.otf: FontAwesome:style=Regular $ fc-match FontAwesome fontawesome-regular.ttf: "FontAwesome" "Regular"
the snippet does not find any of the glyphs. However, removing /usr/share/texmf-dist/fonts/type1/public/fontawesome/FontAwesome.pfb make it work and glyphs get rendered.
