macOS Sequoia added a new PingFangUI.ttc font file which contains all of the PingFang font families. However, any fonts loaded from this font file result in the following failures: - Skia renders font with wrong glyphs - Export to PDF contain a damaged embedded font Despite the fact that the fonts in this new font file have a TrueType font type, they are missing a 'glyf' font table and, instead, have a new, undefined 'hvgl' font table. See the following link for more details about the new 'hvgl' font table: https://gitlab.freedesktop.org/freetype/freetype/-/issues/1281 Change-Id: I18170b1b226de86f79402ad0e45df8620c693f83 Reviewed-on: https://gerrit.libreoffice.org/c/core/+/174305 Reviewed-by: Patrick Luby <guibomacdev@gmail.com> Tested-by: Jenkins Reviewed-by: Jonathan Clark <jonathan@libreoffice.org> Reviewed-by: خالد حسني <khaled@libreoffice.org>
