Crash on Export Qss

[adem4ik]

Preconditions: Windows 10 x64, Python 3.8.2

1. Install QSE via pip install QssStylesheetEditor-1.6-py3-none-any.whl in PowerShell
2. Start by qsseditor
3. Use menu File - ExportQss

Result: QSE crashes, resulting qss-file has 0 size. PowerShell shows the following:

Additional info: According to Russian Stackoverflow the problem related to cp1251 coding. So I've changed line 387 in ui/mainwin.py and that fixed the issue: with open(savefile, 'w', newline='') as f: to with open(savefile, 'w', newline='', encoding='utf8') as f:
