You should set LC_ALL, not LANG.
LANG can be overridden by various LC_* variables;
LC_ALL overrides them all.
And this is particularly true for
-expected_files_after_removal=$(sort <<END
+expected_files_after_removal=$(LANG=C sort <<END
AFAIK, LANG has no effects on `sort` behaviour.
That's not quite accurate. LANG _can_ affect sort behaviour:
$ printf 'gęś\ngoose\n' | env -i LANG=pl_PL.UTF-8 sort
gęś
goose
$ printf 'gęś\ngoose\n' | env -i sort
goose
gęś
This is what POSIX[0] says about LANG:
This variable shall determine the locale category for native language,
local customs, and coded character set in the absence of the LC_ALL and
other LC_* (LC_COLLATE, LC_CTYPE, LC_MESSAGES, LC_MONETARY, LC_NUMERIC,
LC_TIME) environment variables.
