you can try to use this font http://unifoundry.com/pub/unifont/unifont-14.0.01/font-builds/unifont-14.0.01.ttf . I'm currently working on puls verson. It still need some clean up.Probably will be release on this weekend.
i've tested that file and i was correct. You just need to replace the font. Try this one https://www.fontdload.com/downloads/arial-font/ . Rename it to match your old ubuntu font in texreader and overwrite it.
