When tofi returns text with characters such as å, ä, ö it changes when so they are not compatible with the original characters, such as they fail when used in paths.

See this diff, when running the following fish command and pressing enter the diff returns with the 'ö's being different.
`diff (echo ö | psub) (echo ö | tofi | psub) `
