doesn’t work on customer’s website

Assuming you have actually enabled the “French punctuation rules” setting, it is most likely that some plugin produces invalid HTML code. Add add_filter( 'typo_ignore_parser_errors', '__return_true' ); to your functions.php to ignore any parser errors.

You have to clear the cache.

Can you link to a screenshot of your settings and an example page?

Is there any whitespace in your string? If not, the regexes for French punctuation rules won’t match. Test. Test. Test; test (test) should be converted, but not Test.Test.Test;test(test).

If your goal is to enter a sentence without any whitespace at all and have it come out correctly spaced, yes, that is not something wp-Typography was intended to do.

Since apparently your client does not care about heuristics, you could just do a str_replace filter on the content in your functions.php, though.

Well, maybe you need preg_replace to make sure not to mangle any HTML entities.

Something like this (not tested, not optimized) should work:

function spacify( $text ) {
  $text = preg_replace( '@(\w+)(\.|,|;|!|?|\))(^\s)@u', '$1$2 $3', $text );
  $text = preg_replace( '@(\w+)(:)(^\s)@u', '$1 $2 $3', $text );
  
  return $text;
}

add_filter( 'the_content', 'spacify' );
