Hello!

In a buffer starting with ';;; -*- mode: Text; coding: iso-8859-16; -*-' (-r: in the mode-line) and holding the characters in the range 160-255 i-search for € is not successful:

        € = 244 = 164 = A4 = U+20AC = E2 82 AC : EURO SIGN

when I have set:

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

C-u C-x = reveals:

          character: € (01235114, 342604, 0x53a4c, U+20AC)
            charset: [mule-unicode-0100-24ff]
                     (Unicode characters of the range U+0100..U+24FF.)

It too fails for œ and Œ (but works for æ and Æ):

œ = 275 = 189 = BD = U+0153 =    C5 93 : LATIN SMALL LIGATURE OE
