No i-search for ¡, £, ¥ ... in is o-8859-15 coded buffer

[Peter Dyballa]

Hello!

In a buffer starting with ';;; -*- mode: Text; coding: iso-8859-15; 
-*-' (-0: in the mode-line) and holding the characters in the range 
160-255 i-search for €, Œ, œ is successful, but it fails for quite all 
others (I stopped at Â).

£ = 243 = 163 = A3 = U+00A3 =    C2 A3 : POUND SIGN
€ = 244 = 164 = A4 = U+20AC = E2 82 AC : EURO SIGN
§ = 247 = 167 = A7 = U+00A7 =    C2 A7 : SECTION SIGN
 = 302 = 194 = C2 = U+00C2 =    C3 82 : LATIN CAPITAL LETTER A WITH 
CIRCUMFLEX

when I have set:

unify-8859-on-decoding-mode nil
unify-8859-on-encoding-mode t
