Hmmm, after trying: ``` c:>set TEMP="c:\tmp\testfiles\issue1278\ÅÓ¿¼ÑÓ" c:>set TMP="c:\tmp\testfiles\issue1278\ÅÓ¿¼ÑÓ" c:>"\Program Files (x86)\geany\bin\geany.exe" ``` Executing a file doesn't work at all anymore: `21:38:10: Failed to execute "python "main.py"" (start-script could not be created: Datei »"c:\tmp\testfiles\issue1278\ÅÓ¿¼ÑÓ"\geany_run_script_A0N1QY.bat« konnte nicht angelegt werden: Input/output error)` ("konnte nicht angelegt werden" means "file could not be created")
