This is unbelievable !!
But if you work with european mathematicians, you risk to manage 
 all the variants of ISO-8859-x, x = 1, 2, ..., 15

ISO-8859-1 : Germany  Norway 
ISO-8859-2 :  Česká republika
ISO-8859-3 ou 9 : Turkey

For Marc Bœgner in french with -œ- and not  -oe- you need
 ISO-8859-15  "e in o " don't exist in ISO-8859-1.

This a 	junk room a "capharnaüm" in french

Yes you are right it's not a problem to add this line in all my files.
Generally I write
 % encoding utf8
 it will be more correct and salutary to write 
% !TEX encoding = UTF-8 Unicode
