invalid argument ERROR when syncing files that have certain characters in filenames

[zack624]

Hello,

I encountered the "ERROR: invalid argument" when using commands such as:
s5cmd sync /xxx/file\\u3000name.txt s3://bk/
s5cmd sync /xxx/file\\u00a0name.txt s3://bk/
s5cmd sync /xxx/file\\x7fname.txt s3://bk/
It appears that s5cmd does not support processing files with certain characters like \u3000, \u00a0, and \x7f.

When I attempted to use s3cmd or S3 Browser instead, they successfully processed these files.
