Created attachment 187924 [details] Test document When opening a document with an embedded variable font on Linux, only the default instance of the embedded font is available. When the font is installed all defined instances are available. Opening the attached document on a system that does not have Cantarell installed (or while setting the env var SAL_NON_APPLICATION_FONT_USE=deny) should show Regular, Thin, Light, Bold, and Extra Bold font styles, but currently only Regular is available the Bold is synthetic.
On Ubuntu 20.04 without Cantarell installed, I only get the default font styles in the Character dialog: Regular, Italic, Bold, Bold Italic.
