It's actually both:

→ env LC_ALL=C bash -c 'ls -l D[a-z]*'
-rw-r--r-- 1 abe abe 32420 May  9 18:51 Doxyfile
→ env LC_ALL=de_DE.utf-8 bash -c 'ls -l D[a-z]*'
-rwxr-xr-x 1 abe abe 13752 Mai  9 18:51 DOM.xs
-rw-r--r-- 1 abe abe 32420 Mai  9 18:51 Doxyfile
→ env LC_ALL=C dash -c 'ls -l D[a-z]*'
-rw-r--r-- 1 abe abe 32420 May  9 18:51 Doxyfile
→ env LC_ALL=de_DE.utf-8 dash -c 'ls -l D[a-z]*'

My plan is to use something like "find . -name '*[a-z]D.*'" which
seems to be resistent to the above mentioned problem:

→ env LC_ALL=C find . -name '*[a-z]D.*'
./eg/web/indexD.htm
./FeaturesD.pod
→ env LC_ALL=de_DE.utf-8 find . -name '*[a-z]D.*'
./eg/web/indexD.htm
./FeaturesD.pod
→ switchsh env LC_ALL=de_DE.utf-8 find . -name '*[a-z]D.*'
./eg/web/indexD.htm
./FeaturesD.pod

None of the cases above find the POD.pm file:

→ find . -name '*[A-Z]D.*'
./Embperl/Syntax/POD.pm

And just to show what switchsh indeed works and replaces /bin/sh with
bash for a single command (via bind mount):

→ ls -l /bin/sh
lrwxrwxrwx 1 root root 4 Mar 12 10:05 /bin/sh -> dash*
→ env LC_ALL=de_DE.utf-8 sh -c 'ls -l D[a-z]*'
-rw-r--r-- 1 abe abe 32420 Mai  9 18:51 Doxyfile
→ switchsh env LC_ALL=de_DE.utf-8 sh -c 'ls -l D[a-z]*'
-rwxr-xr-x 1 abe abe 13752 Mai  9 18:51 DOM.xs
-rw-r--r-- 1 abe abe 32420 Mai  9 18:51 Doxyfile
