"""
Returns a translation table to remove invalid characters for a specified file system type.
This function identifies the file system type and returns a translation table for removing
characters that are not allowed in filenames for that specific file system.
Args:
file_type (str): The type of file system being checked. Supported file systems include:
- Windows: NTFS, FAT32, exFAT, ReFS
- Linux: ext2, ext3, ext4, Btrfs, XFS, ZFS
- macOS: APFS, HFS+
- BSD/UNIX: UFS
- Network Filesystems: CIFS, SMB
Returns:
dict: A translation table where invalid characters are mapped to an empty string.
Example:
>>> ys = yt.streams.get_highest_resolution()
>>> ys.download(file_system='ext4')
Raises:
None, but prints a message if the file system type is not recognized.
