Bug fix #3096 at line 155 in Contributor.pm no longer works.  It is currently:

[code]
			# Bug 3069: update the namesort only if it's different than namesearch
			if ( $search ne $sort ) {
				$sth = $dbh->prepare_cached('UPDATE contributors SET namesort = ? WHERE id = ?');
				$sth->execute( $sort, $id );
			}
[/code]
The problem is that at some point, the sort form was extended to included accented characters (in lower case) whereas the search form never includes accents (although the characters that are accented in the sort form are in lower case).

So for accented default sort forms $search is always 'ne' $sort.  This means that perfectly good sort forms derived from ArtistSort get overwritten when, for instance, an Artist is also a Composer or Conductor and brings a default sort form.  This is was the original good bug fix was meant to do.

I did a test run with a 'bodge' to prove my theory, and it worked.  I just did:
[code]
    if ( substr($search,0,3) ne substr($sort,0,3) ) {
[/code]
On the basis that for most of my problem artists the accents are later in the name.

What is needed is a proper fix knowing how and why the default sort and search forms are different for accented names, and a function to make the comparison work properly.  I thought of trying 'unidecode' but my Perl knowledge, and multi-language unicode knowledge, are both close to zero. so I thought better of it.

Without this fix, Artist and AlbumArtist menus in LMS are in a random order for many of my artists, and very frustrating to try and use.
