Avoid repeated inode numbers.

It is not recommended to use a * to remove files. It could match more than you like.

Being in Debian, the ls (from GNU) command is able to print the values of the files in quoted form[1]:

$ ls -Q
"\nssolve"  "\n\nssolve"  "y"  "z"

Or, even better, list files with quoted names and inodes:

$ ls -iQ
26738692 "\nssolve"  26738737 "\n\nssolve"  26738785 "y"  26738786 "z"

Then, use rm with the inode number to ensure that only the correct files are removed:

$ find . -xdev -inum 26738737 -exec rm -i {} \;

The call to find is limited to one filesystem (-xdev) to avoid matching a file on other filesystem with the same inode number. Note also that rm is being called with the -i (interactive) option, so it will ask in the command line if each file should be erased.

[1] Note that this do not solve the problem with visually confusing characters like a Cyrillic а ($'\U430') and a Latin a ($'\U61') that look exactly the same but are not. To have a better look at the bytes that a filename is using we need to use an hex viewer;

$ touch а a é $'e\U301' $'\U301'e
$ ls
a  ́e  é  é  а              # what you "see" here depends on your system.

$ printf '<%s>' * | od -An -c
   <   a   >   < 314 201   e   >   <   e 314 201   >   < 303 251
   >   < 320 260   >
