I encountered a strange problem. If I set the Title of an image with Asian characters (including Chinese, Japanese, etc.), the gallery can function well. But when I download the image, then upload this image directly to an other folder, the Title shown in the panel becomes "????". I have noticed that the metadata in the downloaded image also becomes "????".
I guess this problem is because of character encoding. Although it is good when I do not move these images, I want to know if anything I can do to fix it? Thank you.
