I happen to have this font on my system (Windows 7). So I used the same tool and generated the font, using the default charset. It made a 16KB file.
Now, I had an issue with this font. I recently installed LibreOffice, which came with a number of fonts, including, probably, this one. Then I found that a number of pages I browsed in Firefox displayed numbers (Unicode code-point in a small square) instead of text! I found out the page defined the font as DejaVu (among others, but it was the one picked up).
I went to the Fonts folder, moved out these fonts, downloaded the latest version of DejaVu (it is an open source font) and installed it, and the problem disappeared...
I wonder if you have a similarly "corrupted" font issue.

Perfetc!

Thank a lot. The error is gone.

Bur nothing on the screen, no view of signal, nothing move.

I use an Arduino Mega2560 and the sources : http://code.google.com/p/arduinoscope/

Have you an idea?

It is a different problem and I know nothing about Arduino. But if you suspect it is because of the font, you should try a small sketch using it and see if it works.

I found!!

After instal the library, RXTX, like explain here : https://forum.processing.org/topic/rxtx-version-mismatch

The message below confirm instal

Stable Library
=========================================
Native lib Version = RXTX-2.1-7
Java lib Version   = RXTX-2.1-7
[0] "COM3"
[1] "COM4"
[2] "COM5"

But, you have to change the number of the serial in the soft here :
        //CHOOSE PORT HERE
    myPort = new Serial(this, Serial.list()[2], 115200);

Don't forget to change the speed of the serial in arduino with the serial monitar by 115200

It's works
