Thanks, as expected, the issue is not with `sed`. Instead it is `tree` 
which has some odd default behaviour in that it “escapes” (mangles) 
characters (byte sequences) it deems “unprintable”.

     % mkdir test && touch test/Æblegrød && tree test
     test
     └── ?\206blegrød

This can be changed by passing the `-N` option:

     % tree -N test
     test
     └── Æblegrød

Please verify that adding `-N` to `tree` works for you, and if so, I 
suggest updating your patch to use this solution instead of changing the 
locale.
