Hello, I am trying to compile the example provided by khaled hosny https://github.com/khaledhosny/xits-math/blob/master/test-suite/arabic.tex. However this is what I get fonts           > virtual math > unable to resolve name mapsfromchar fonts           > fallback modern rm 12pt is loaded system          > begin file arabic.tex at line 5 Missing character: There is no ف (U+0641) in font lmroman12-regular! I have the latest version of livtex. When I run mtxrun --script fonts --list --all --pattern=xits xits   xitsbolditalic   xits-bolditalic.otf which is strange because the font xits-math is not listed I have noticed that xits is already installed with livtext, and I have followed the instruction in this page to 'http://wiki.contextgarden.net/Fonts_in_LuaTeX' install the fonts in and I have also installed the fonts in the home_directory/ .fonts I was able to use the xits math with lualatex and it worked fine. luaotfload | load font: font family='xitsmath', subfamily='regular' found: xits-math.otf Thanks in advance
