Within a ``guix shell --pure less'' environment, the “less” command
does not display UTF-8 characters properly:
Toggle snippet (5 lines)
~/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?
Answering the prompt with 'y' will display:

This can be worked around by setting the LESSCHARSET environment variable:
Toggle snippet (3 lines)
~/src/guix [env]$ LESSCHARSET=utf8 less gnu/packages/java-xml.scm
Which will correctly display (without any prompts):
Toggle snippet (14 lines)

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.
