Unfortunately, some accounts are currently not unique across all our

in future, we will be renaming a number of accounts to have "~” and
the name of their wiki added to the end of their accounts' name. This
change will take place on or around 27 May. For example, a user called
“Example” on the Swedish Wiktionary who will be renamed would become
“Example~svwiktionary”.
Why did you choose to insert the character "~"? Many keyboards do not
have
such a key.
