I noticed today that when sending G-code printer (Octoprint) application crashes. If it is discovered fail with STL if was originally a Cyrillic name. When attempts through the web interface octoprint pour gcode he gave an error in the title of the Cyrillic (or rather that he does not understand the file format), but slic3r just took off without telling anything.
slik3r 1.2.7 dev
As an option, it makes sense to convert the file name, when you send to the printer. For example Cyrillic transliteration in Latin script
Handle OctoPrint upload of files having Unicode characters in filenam…
…e or path. #2827
Thank you, I fixed this.
