In the upper right corner of the screen, right beside the clock, you can open the character table which opens a window with a lot of different characters, sorted by categories (currencies, arrows, math symbols, ...). Now my question is how can I know which font serves one specific symbol? For example if I insert the arrow "RIGHTWARDS ARROW FROM BAR" I get only a questionmark in my text. Obviously my font does not contain this symbol but how to know which font DOES contain it? I don't have to try all my 200 fonts, do I? Thank you!
