What do you recommend to use for viewing fonts including the glyph, extras, and others in Linux? I need to see the Unicode for the glyph and special characters.
How about GNOME Character Map (
gucharmap)? It shows information on every Unicode character and allows you to choose the font for glyph display.
Why don't you try FontForge? Besides of making fonts, FontForge can also display preview of any fonts you have installed. It's free and available on Windows & Linux
