Sorry for wrong information in last message. Actually the font setting
code above doesn't work in daemon.

runemacs --daemon
OR
 ./emacsclientw.exe --alternate-editor= -n -e "(raise-frame )" &

Then a popup window with:
```
A fatal error has occurred!

....

(type "gdb -p <emacs-PID>" and "continue" inside GDB before clicking YES.)
```
