Common issue with RPG Maker games; navigate to directory with nw binary
mkdir fonts; echo '<fontconfig><dir>/usr/share/fonts</dir><cachedir>fonts</cachedir></fontconfig>' > fonts/fonts.conf; FONTCONFIG_PATH=fonts ./nw
Thank you very much. This works! So now I'll have to launch the game like this every time?
First two commands are one-time use; the variable is important; you have multiple options for last line like adding alias in shell rc, exporting variable in shell profile or creating .desktop file
