Can't open file if the path contains non-ANSI characters

Suppose I have a file in the following path:
C:\樂譜\my_score.mscz

If I open File Explorer at C:\樂譜\ and double-click on my_score.mscz, MuseScore would just report that it's unable to open the file. If I open MuseScore first and then go to File > Open... and open the same file, this will work just fine. This is because my Windows is set at English, not Chinese.

This problem is actually quite common and I have come across it in many different applications. Some managed to do some change in programming to support this with the use of Unicode support. An example is IrfanView.
