How to reproduce

Edit some GCODE in the GCODE editor (the actual editor, so click the edit button above any GCODE section, the editor that shows all the placeholders and actually uses a fixed-width font)
Put some symbols in there - I was trying the degree symbol - ° (followed by C, of course)
Save
Re-open editor
Observe corruption
Save - without changing anything
Re-open editor again
Observe even more corruption and random chars appearing
Rinse/repeat, it will keep adding chars.

Actual results

Was wondering why my logs had weird symbols, so looked, went and fixed the gcode, hit save, re-opened it and this:

Expected results
