As you say: "it makes no sense why 2 will work but 3 or

(new File(dir,"<e acute><e acute>.html")).exists() and
(new File(dir,"<e acute><e acute><e acute>.html")).exists()

(first one returns true - I was wrong saying the contrary in my first message, sorry - and second false)

That's why I came to thinking that the problem is in fact in the way the OS handles "accent decomposition".

It definitely looks like it's accent decomposition. I tried this code:

testFile("\u00e9.html");

testFile("\u00e9\u00e9.html");

testFile("\u00e9\u00e9\u00e9.html");

String[] files = new File(".").list();

for ( int i = 0; i < files.length; i++ ) {

String s = files[i];

if ( s.endsWith(".html") )

testFile( s );

}

static void testFile( String s ) {

System.out.println( s +": " + new File( s ).exists() );

for ( int j = 0; j < s.length(); j++ )

System.out.print( (int)s.charAt(j)+" " );

System.out.println();

}

and got the output (characters mangled by the Xcode console):

\216.html: true

233 46 104 116 109 108

\216\216.html: true

233 233 46 104 116 109 108

\216\216\216.html: false

233 233 233 46 104 116 109 108

e.html: true

101 46 104 116 109 108

e?.html: true

101 769 46 104 116 109 108

e?e?.html: true

101 769 101 769 46 104 116 109 108

e?e?e?.html: true

101 769 101 769 101 769 46 104 116 109 108

The composed accents from the original strings sometimes work and sometimes not, but if you list the files in the folder the names have decomposed accents and they work OK.
