Your problem most likely doesn't stem from the "OpenSans" font you specified - since I doubt it covers any Chinese glyphs - but instead from whatever the fallback font on your KUbuntu system. Unfortunately, I don't know any easy way to identify this fallback font in LO. The workaround is to specify a font that's known good for displaying Chinese characters, like "Noto Sans CJK HK" in your second file. You can always specify separate fonts for Latin and Chinese text if you prefer OpenSans for its Latin and digital glyphs. FWIW, on my Windows 10 system with LO 6.4.3, I can open both attached files without any slowdown. I have neither "OpenSans" or "Noto Sans CJK HK" fonts installed (I have "Source Han Sans SC" instead).</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
