bug#41488: 26.3; Cyrillic chars in output of find-dired and find-name-dired looks like '\234\188\123'

[Viktor Larkin]

Hello.

I've no idea what causes this bug, but... When I do recursive search
with find-dired or find-name-dired with cyrillic chars as search pattern
(e.g. документ) I always get something like '\234\221\123' instead of
correct cyrillic chars in file names and file paths. To reproduce:

1. emacs -Q

2. C-x d

3. M-x find-name-dired

4. RET

5. документ*.txt

6. RET

Output of locale in terminal and in eshell is the same. ru_RU.UTF-8 is a
chosen encoding for LANG and LC_CTYPE. Emacs version is 26.3. GNU findutils
version is 4.7.0.

I've found this topic
https://www.reddit.com/r/emacs/comments/bvuv9q/cyrillic_letters_dont_work_with_find_in_emacs/eptkhsr/
. Seems like bug is still in the wild.
