Printing Over the Network

[XYZDesignPro 70]

Discovered something interesting about printing over the network in Cura 4.0.0.  I had occasion to name a file using the upper ASCII character ¾.  I modeled a bottle that was 3/4 oz Oval Bottle in SolidWorks.  Not surprisingly, SWX would not let me save it using the slash / between the 3 and the 4.  So, I used the upper ASCII character ¾ (key stroke Alt + 0190 using the numeric key pad).  SWX saved the file just fine.  Now when I tried to send the file over the network from Cura to my UM3 it said it sent it successfully, but it never printed.  Looked in Cura Connect.  It was in the ques, but not printed.  Numerous attempts to force it to do so failed.  I then saved the file out of Cura to the USB drive, put the drive into he printer and it printed just fine.  I guess the upper ASCII character violates network protocols?
