mount command can not contain Chinese characters

I encounter a problem,

I want to mount a shared remote directory, but the url has Chinese characters.

mount_smbfs //user:password@192.168.1.168/图片 /Volumes/picture

图片are Chinese characters, which mean picture in English.

When I execute this command, I get below error:

mount_smbfs: URL parsing failed, please correct the URL and try again: Invalid argument 16384

I can confirm it is caused by the Chinese character, because I can execute below command: mount_smbfs //user:password@192.168.1.168/hehe /Volumes/picture

Both hehe and 图片 are remote shared directories.
