Right, it works a bit, i.e. in the ASCII range it works well. When it  
comes to ISO Latin it interprets all in ISO Latin-1, i.e. C-s C-q 0 0  
a 4 RET searches in an ISO 8859-16 encoded buffer for CURRENCY UNIT  
although it is EURO in this case. A translation to the buffer local  
encoding obviously does not happen ...


(setq read-quoted-char-radix 16)
(setq read-quoted-char-charset 'ucs)

After applying your patch this behaviour does not change, it's still  
assumed that the encoding is ISO Latin-1. 00A4 is categorically ``¦ 
´´. The improvement is that I can find via an Unicode value an ISO  
Latin encoded character – is this an improvement? The file code is A4  
in any ISO Latin case, and the character is U+20AC in Unicode when in  
ISO Latin-10/ISO Latin-0 or ISO Latin-9. This looks like a Do What I  
Mean. Really not bad! But the real way should be C-s C-q 2 4 4 RET or  
C-s C-q A 4 RET or C-s C-q 1 6 4 RET (decimal), because it searches  
for the codes one expects in the encoded file, and which does not work.
