If your font isn’t showing up like it should there’s a pretty easy way to fix and troubleshoot this using three of the Converter command-line options.
--output_model_info
This command will output a text file that contains the specific fonts that may be missing.--prc_font_directories
This option allows you to specify where to find these fonts.--substitution_font
This final option can replace your current font with a new one if you want to change out the font.
