Try:

$ LC_CTYPE=anything.ISO-8859-2  guix repl é
hint: Consider installing the `glibc-locales' package and defining 
`GUIX_LOCPATH', along these lines:

     guix install glibc-locales
     export GUIX_LOCPATH="$HOME/.guix-profile/lib/locale"

See the "Application Setup" section in the manual, for more info.

;;; Stat of /home/[...]/ĂŠ failed:
;;; In procedure stat: Bestand of map bestaat niet: "/home/[...]/ĂŠ"
guix repl: fout: open-file: Bestand of map bestaat niet: 
"/home/regulator/source-code/rw/ĂŠ"

IIUC, this causes lib/localcharset.c in Guile to run 'eviron_locale_charset',
which just uses environment variables and ignores glibc's locale data.

I don't know if this requires 'setlocale' or requires the absence of 
'setlocale'.

Greetings,
Maxime.
