what is this supposed to do?  I don't have such a file ...

yes, that' the right thing to do (R) ;-)

where do you do the hyphenation???

It is for changing the _input_encoding!  It's a little bit confusing that 
there is no differentiation between input and output encoding.  "ec" is an 
output encoding used to map internal codes to external ones.  "pro" is a 
special case, cause it is needed for protruding (that is something I don't 
understand in depth ...).  "win" is an input encoding.  So maybe "\input 
xhyphen" uses some characters that are remapped by "win".

Though "win" is a name I don't like ;-)  it now is the right encoding when 
"mostly ansi 8859-1" is meant.

Yes, if you think from the ansi 8859-1 direction.  The characters in AER 
are mapped with the T1 encoding.  An if you think about the presentation of 
characters for computers -- they don't see the glyphs, they only see a 
number, and a convention (an encoding) is used to associate glyphs with 
this number -- you may finally be able to understand the problem:

You enter your text in a specific encoding (for nearly all western 
encodings the codes for the ASCII section are the same, so an "A" is an "A" 
is an "A" ;-)) and the fonts you use have another one.

Hope this helps
Uwe
