The 0xc2 seems to have gotten into the file while sending it.  It is
not there in the original and can be deleted without affecting the
outcome of choosing a coding system.

Really?  In my case this results in

,----

|     charset: [mule-unicode-0100-24ff]

|      -Misc-Fixed-Bold-R-Normal--18-120-100-100-C-90-ISO10646-1 (0x44C)

for the u umlaut and

for the Euro sign.

For the record, the following is what I get if I load the file without
specifying a coding system before (i.e. when it ends up being
displayed with raw-text-dos):

,----
|   character: ü (0374, 252, 0xfc)
|     charset: [eight-bit-graphic] (8-bit graphic char (0xA0..0xFF))
|  code point: [252]
|      syntax:          which means: whitespace
| buffer code: 0xFC
|   file code: 0xFC (encoded by coding system raw-text-dos)
|     display: by display table entry [?ü] (see below)
| 
| The display table entry is displayed by these fonts (glyph codes):
| ü: -Bitstream-Terminal-Medium-R-Normal--18-140-100-100-C-110-ISO8859-1 (0xFC)

,----
