Error with loading .mscz files with Korean character

If there is no Korean character in both foler and filename, it works well.
After loading 'musescore' and first open the .mscz file(1st file: it can contain Korean character), it’s opened well. But that's all. When trying next file which contain Korean character, i met the same message as shji69 and hjkong,
When I try to open the .mscz files with Korean character by double_clicking, the only the 1st file (which I opened just before) can be opened. Others show the same error message.
폴더와 파일이름이 모두 영문이면 문제가 없습니다.
한글이 포함된 경우 직전에 musescore를 띠우고 처음으로 연 한글을 포함파일은 열리지만 그외의 것은 열리지 않고 shji69 and hjkong께서 올린 에러를 내고 있습니다,
