There is an issue in the software of the Anet A8 printer, that causes a break in printing, if there is a special character in the G-code; e.g. something like the German ä, ö and ü just let the Anet A8 stops working.

This character can get into the G-code file through Ultimaker Cura, that insert comments like

;MESH:Loki_hörner_v2.stl

into it.
