you were right, the server uses "lc_collate en_US.utf8".
quite amazing situation.
As you mentioned, I replaced the column type (bytea instead of varchar) and
some code (text2code128 now returns bytea instead of text, using decode
function).
I have been able to insert my data without problem
Then, before creating my barcode labels, I use the decode function to change
the binary data to text data, and that's it.
I really appreciated your help.
Have a nice week-end

What locale are you running the server in? It's possible that these
strings are equal according to the locale-specific strcoll() behavior.
In particular, if you are using a locale that expects UTF8, it's pretty
common for strcoll to go nuts when faced with non-UTF8-legal strings.
You might be better off using bytea instead of varchar.
