### Basic Information:

Printer Model: Voron 2.4 300  
 MCU / Printerboard: Spider 1.1  
 `klippy.log`

[klippy.log.zip](https://klipper.discourse.group/uploads/short-url/wTYXKbaojDee0svIdGzqNgne3rn.zip) (94.0 KB)

### Issue:

I’m trying to print the following gcode:

> **[Peca1-Gunbody\_FINAL-ABS+-eSun.gcode.zip](https://drive.google.com/file/d/1gnfdKjvr-iWuYnKcv4XsITWMB6lAo53C/view?usp=sharing)**
>
> Google Drive file.

Trying to start the print crashes klipper on unhandled exception.

I’m happy to provide whatever additional information might be needed.

You seem to be using special characters like in `Peça1` in your gcode.  
This is currently a known issue. Avoid such characters.
