Subject: UTF-8 support absent within guix shell --pure less
Date: Sat, 20 May 2023 15:17:12 +0100

Within a ``guix shell --pure less'' environment, the “less” command
does not display UTF-8 characters properly:
--8<---------------cut here---------------start------------->8---
~/src/guix$ guix shell --pure less
~/src/guix [env]$ less gnu/packages/java-xml.scm
"gnu/packages/java-xml.scm" may be a binary file.  See it anyway?
--8<---------------cut here---------------end--------------->8---

Answering the prompt with 'y' will display:
--8<---------------cut here---------------start------------->8---

--8<---------------cut here---------------end--------------->8---

This can be worked around by setting the LESSCHARSET environment variable:
--8<---------------cut here---------------start------------->8---
~/src/guix [env]$ LESSCHARSET=utf8 less gnu/packages/java-xml.scm
--8<---------------cut here---------------end--------------->8---

Which will correctly display (without any prompts):

This does not happen with a non-pure ``guix shell less'', it properly
shows UTF-8 characters without having to manually set any environment
variables.
Adding glibc-locales to ``guix shell --pure less glibc-locales''
does not help either and in neither environments is GUIX_LOCPATH set
as it was suggested at <https://logs.guix.gnu.org/guix/2023-05-20.log#035013>.

So GUIX_LOCPATH is *not* set, right?  Could you try adding 'glibc' to
the environment as well?  It's the one providing the GUIX_LOCPATH search
path.

The issue still remains (with and without glibc-locales):

--8<---------------cut here---------------start------------->8---
~/src/guix$ guix shell --pure less glibc glibc-locales
~/src/guix [env]$ less gnu/packages/java-xml.scm
"gnu/packages/java-xml.scm" may be a binary file.  See it anyway? 
…

~/src/guix [env]$ echo $GUIX_LOCPATH
/gnu/store/654wv1gyw1r2gpcwggmn8spbcrq5b9vq-profile/lib/locale
--8<---------------cut here---------------end--------------->8---

Furthermore, I consider that nonfree software must be eradicated.

Cheers,
Bruno.
