You might want to try adding a suitable mount option there.  Not sure if
it's mounted as FAT or VFAT or whatever, but scour the options part of
the appropriate manual page.

Here `convmv` might come in handy.  I often use that to clean up the
"mess" after extracting zip archives with Shi*t_JIS file names on a
UTF-8 using file system.  Guessing your "horribly weird characters" are
ISO-8859-{1,4,10,15}, (or whatever IBM code page Microsoft saw fit to
appropriate for those).

That `~1` looks a lot like you are actually dealing with a VFAT file
system.  How do things look after a

  mount -t vfat /dev/sdb1 /media/hendrik/

On any Unix-like system I've come across the '/' (and '\0') are about
the only character that cannot be used in a filename.  As mentioned
above check the mount.vfat (or mount.fat or mount.cifs?) manual pages
for options that might transparently "fix up" the file name.

# Yes, you can use `\n` in a file name ... but please don't.

It's an SD card, right?  Asking a friendly neighbour to rename the
file(s) in question may be the quickest way out of your conundrum.

Hope this helps,
