This is strange since \"e becomes \eumlaut and this is mapped onto a glyph 
number; are you sure that pdftex does not report a missing map file?

for fonts you need:

(1) tfm/vf files
(2) type1 (pfb) files
(3) a map file
(4) to let context know what input/output encoding you use

when using fonts that match your key codes it may go well without noticing 
that in fact the system is set up wrong [this is i thing one reason for 
frequent errors in files

So, try to determine what happens with 1-4; especially (3) is organized 
rather messy in tex distributions due to incompatibilities in map files 
between dvips and pdftex and dvipdfm [currently texfont handles pdftex and 
i will handle the others later]

It can be very illustrative to say \showfont[Serif] so that you get an idea 
what font is used in what encoding. One reason to change context's defaults 
to more verbose low level font names is to catch problems like this.

[in a couple of days you may test the next beta, which is now fully 'new 
name' aware and [when set up ok] handles all map files itself. in that case 
you can generate all metrics you need for a specific encoding with one command]

[there are some remaining problems that i want to discuss with thanh first]
