Description Martin Birgmeier 2026-06-05 14:58:22 UTC 
Scenario:
- FreeBSD stable/15 at 6146c5962e5c
- LANG environment variable set to C.UTF-8
- No LC_* environment variable set
- The filesystem (ZFS) is using UTF-8 character encoding for filenames
- Running md5 -r копия.doc

Result:
- The following is output:

0123456789abcdef0123456789abcdef \320\272\320\276\320\277\320\270\321\217.doc

Expected result:
- The following should be output:

0123456789abcdef0123456789abcdef копия.doc

Note:
- In /usr/src/sbin/md5/md5.c, the function "safename()" is used to mangle filenames. This should be replaced by a saner check which also considers international characters based on the environment settings for LANG and LC_*.
