Hi!
----
Below is a testcase which shows a problem with the handing code for
LC_*/LANG variables.
AFAIK the problem looks like this:
If I set LANG to a value, then set any of the LC_* variables to
(partially) override LANG and then unset (or set it to '' (empty
string)) the LC_* variable |setlocale()| is not being called to restore
the locale settings defined via the LANG variable.
The testcase looks like this:
-- snip --
export LC_ALL=en_US.UTF-8
printf "\u[20ac]\u[20ac]" >two_euro_chars.txt
unset \
LC_COLLATE \
LC_CTYPE \
LC_MESSAGES \
LC_MONETARY \
LC_NUMERIC \
LANG
(
cat <<EOF
export LANG=en_US.UTF-8 LC_ALL=C
wc -C < two_euro_chars.txt
unset LC_ALL
wc -C < two_euro_chars.txt
export LC_ALL=C
wc -C < two_euro_chars.txt
EOF
) | x="$(/usr/bin/ksh93)"
[[ "$x" == ~(E)[[:space:]]*6[[:space:]]*2[[:space:]]*6 ]] || \
printf "expected \$' 6\\\n 2\\\n 6', got %q\n" "$x"
-- snip --
AFAIK the output should be "6 2 6" but for ast-ksh.2009-09-08 the
testcase above prints "6 6 6" ...
This happens for any of the LC_* variables overriding LANG and LC_ALL
overriding both the other LC_* variables and LANG...

Bye,
Roland
