Hi,

I was able to reproduce this from the cuirass checkout when unsetting
LANG and that indeed seems to be issue, is there a reason why UTF-8 is
not the default in shepherd/guile/cuirass?  IMO it would be better to
set it to the default to avoid future issues with other services.

What do you think?

The specification to reproduce:
(list (specification
       (name 'bloup)
       (channels
	(cons (channel
	       (name 'bloup)
	       (url "https://framagit.org/nll/bloup.git")
               (branch "cuirass-bug")
	       (introduction
	        (make-channel-introduction
	         "f627568549edd28c97dded5e5ec985cd11e95f58"
	         (openpgp-fingerprint
	          "5D54 CF25 57B2 38E8 8DC1 80A2 2D22 3241 0AB7 4043"))))
	      %default-channels))))
