Alcohol 120% doesn't like non-English character on file path

I had problem making an ISO image properly loaded by Alcohol 120% (Version 1.9.2, Build 1705). The disc was loaded without error, but it couldn't be mounted properly. Later I realized that the ISO image is inside a directory which the directory was in Chinese character. Moving the file out of the directory solved the problem. So I guess Alcohol 120% doesn't like non-English character on file path.
