Hi

When I use the FreeSerif and FreeSans fonts, I notice strange 
overlappping with words containing vowels with circumflex, such as â, ê, 
î, ô, û and  Â, Ê, Î, Ö, Ü.

I made a test case to show you, I hope attachments are allowed here.

Thanks.

nb: No problem with FreeMono, but I suspect monospaced fonts can't have 
such problem.
nb: There is no such problem when I use the Xetex engine.
