Hi.

I have noticed that sort seems to have problems when the LANG environment
variable is set with language and country.

As a test case, i tried to sort

a
b
a
⺌
⺕
⺌

It sorts OK like this, with LANG just the language.encoding:
( setenv LANG en.UTF-8 ; echo 'a\nb\na\n⺌\n⺕\n⺌' | sort )
a
a
b
⺌
⺌
⺕

But not with LANG as language_country.encoding:
( setenv LANG en_GB.UTF-8 ; echo 'a\nb\na\n⺌\n⺕\n⺌' | sort )
⺌
⺕
⺌
a
a
b




sort: sort (GNU coreutils) 8.21
Shell: tcsh 6.18.01 (Astron) 2012-02-14 (x86_64-unknown-linux) options
wide,nls,dl,al,kan,rh,color,filec
