Your patch couldn't detect 0xA0 in config.sgml in my machine, but it works
when I use `grep -P "[\xA0]"` instead of `grep -e "\xA0"`.

However, it also detects the following line in charset.sgml.
(https://www.postgresql.org/docs/current/collation.html)

For example, locale und-u-kb sorts 'àe' before 'aé'.

This is not non-breaking space, so should not be detected as an error.
