Hello!

When pasting a copy of a filled in text from OmniWeb (a Web browser  
coming from the NeXT) into a file buffer in GNU Emacs (mode-line  
starts with -U:), which was launched with -Q, the German umlauts ä,  
ö, ü, Ä, Ö, Ü are stripped off their diaereses and mutate to a, o, u,  
A, O, U. Typing C-u C-x = on such a Marcel Duchamps character leads  
to an error message in echo area:

	Format specifier doesn't match argument type

In *Messages* buffer a ``describe-char: ´´is prepended the text.

In dired buffers the same umlauts in file names are stripped, while  
the date fields can display an abbreviated month's name as ``Mär´´.  
Typing on this ä C-c C-x = I get:

	        character: ä (228, #o344, #xe4)
	preferred charset: iso-8859-1 (Latin-1 (ISO/IEC 8859-1))
	       code point: 0xE4
	           syntax: w 	which means: word
	         category: j:Japanese l:Latin
	      buffer code: #xC3 #xA4
	        file code: #xC3 #xA4 (encoded by coding system utf-8-unix)
	          display: by this font (glyph code)
	     -B&H-LucidaTypewriter-Medium-R-Normal-Sans-10-100-75-75-M-60- 
ISO8859-1 (#xE4)
	
	Character code properties are not shown: customize what to show
	
	There are text properties here:
	  auto-composed        t
	  fontified            t

instead of an error message. The error message is output when I type  
on as tripped umlaut in a file name!


Looking with GNU Emacs 23.0.50 into the file saved with its stripped  
umlauts I see instead of them ``{äöüÄÖÜ}<an open box>´. This box is  
described in GNU Emacs 23.0.50 as:

	        character:  (332488, #o1211310, #x512c8, U+0308)
	          charset: mule-unicode-0100-24ff
			   (Unicode characters of the range U+0100..U+24FF.)
	       code point: #x25 #x48
	           syntax: w 	which means: word
	         category: ^:Combining diacritic or mark
	      buffer code: #x9C #xF4 #xA5 #xC8
	        file code: #xCC #x88 (encoded by coding system mule-utf-8-unix)
	          display: by this font (glyph code)
	     -b&h-lucida sans typewriter-medium-r-normal--10-98-74-74-m-60- 
iso10646-1 (#x308)
	     Unicode data:
	             Name: COMBINING DIAERESIS
	         Category: non-spacing mark
	  Combining class: Above
	    Bidi category: Non-Spacing Mark
	         Old name: NON-SPACING DIAERESIS
	ISO 10646 comment: Dialytika
