Is related to QA614

Test done with flamerobin, though also fails from jaybird:

recreate table test1 \(field1 varchar\(50\)\);

insert into test1 values \('PABLO NUÑEZ SANCHEZ'\);

update test1 set field1=replace\(field1,'Ñ','N'\);

select \* from test1;

and you obtain "PABLO NÑN SANCNZ" instead of expected "PABLO NUNEZ SANCHEZ". I other situations we obtain an OOM error from firebird or even get a server crash, here is server log:

PALEVI-XPS (Server) Fri Nov 07 13:10:53 2014

The code attempted to access a virtual
address without privilege to do so.

====== Test Details ======

Integral test for comparison latin-1 characters with diacritical marks and their ascii-equivalents, all kinds of string matchin.
NOTE: following are letters which currently do NOT pass comparison using accent insensitive collation:
Ø = U+00D8 // LATIN CAPITAL LETTER O WITH STROKE' (U+00D8), used in danish & iceland alphabets;
Ð = U+00D0 // LATIN CAPITAL LETTER ETH' (U+00D0), iceland
Ŀ = U+013F // LATIN CAPITAL LETTER L WITH MIDDLE DOT' (U+013F), catalone (valencian)
Ł = U+0141 // LATIN CAPITAL LETTER L WITH STROKE' (U+0141), polish.
