Multibyte characters (i.e., Japanese) appear in volume label of partition of a drive causing error

[e-perl-NOAA]

This issue is for record keeping of a problem that someone with FRA encountered trying to download the SAC Tool.

Error

The cause was multibyte characters (i.e., Japanese) appeared in a volume label of a partition of a drive in the machine.

After deleting the characters (i.e., empty volume label), the app was properly launched.

I suspect that when shiny searched for a label of each volume, the multibyte characters caused an error.

I referred to the link above and detected the multibyte characters by using the following method in the Powershell.

[System.IO.DriveInfo]::GetDrives()

When I divided the C drive into two partitions at the initial setup of the machine, the multibyte-character volume label was automatically set for a new partition.
