Hello.
The reason for the garble turned out.
The default template is used.
Only when HFS is seen from a browser, the garble's happening :.
Encode is UTF-8.
When encode is shift_JIS, it is seen normally.
However, in either case of UTF-8 and shift_JIS
When the folder with the file that gives a Japanese name is sorted, it is not possible to
download it. (404)
When it is made a virtual folder, this is not generated.
This is not generated for the file name of English and the figure.
Why do you understand?
Postscript
There is a volunteer who is making it to Japanese by using the source file. Will you become a language file format HFS?
