Problem with reading non-english letters

After updating to version 4.4.0, I couldn't open any .mscz files had non-English letters or .mscz files that were in folders/subfolders that had non-English letters like ä, ñ, č, š, ע etc. The warning I got said ''Cannot read file, this file does not exist or cannot be accesed at the moment''. I renamed the files and folders/subfolders to remove all the non-English letters and now they can all be opened up without a problem. I'm putting this out here so that in case you get the same problem with a file that has non-English letters in its filename or is in a folder that has them, try renaming the file/folder. It could help fix the issue.
