Bug description: chinese comparision in delphi 5 COM object
Description:
------------
I wrote a COM object by using delphi 5.
It do some comparision in the delphi object like the following code.
====================================================
function Ttest.comparestr(const a, b: WideString; c,
d: OleVariant): OleVariant;
var
e : widestring;
r : olevariant;
begin
e := '中文';
r := '';
if a = b then
r := r + 'a=b<br>'
else
r := r + 'a<>b<br>';
if c = d then
r := r + 'c=d<br>'
else
r := r + 'c<>d<br>';
if a = c then
r := r + 'a=c<br>'
else
r := r + 'a<>c<br>';
if a = e then
r := r + 'a=e<br>'
else
r := r + 'a<>e<br>';
if c = e then
r := r + 'c=e<br>'
else
r := r + 'c<>e<br>';
result := r;
end;
====================================================
It always shows a<>e and c<>e(others equal) when I use PHP COM funcion,
and do chinese comparision. But It prints all equal if I send pure english
words or some numeral vairants.
And It shows all equal while I using asp to call the COM object, whatever
I send chinese or english.
Reproduce code:
---------------
<?php
$a = $b = $c = $d = "中文"; //some chinese words
$comtest = new COM("comtest.test1");
echo $comtest->comparestr($a, $b, $c, $d);
unset($comtest);
?>
php outputs:
a=b
c=d
a=c
a<>e
c<>e
=================================
<%
a = "中文" 'some chinese words
b = a
c = a
d = a
set comtest = server.createobject("comtest.test1")
response.write comtest.comparestr(a, b, c, d)
set comtest = nothing
%>
asp outputs:
a=b
c=d
a=c
a=e
c=e
Expected result:
----------------
output:
a=b
c=d
a=c
a=e
c=e
Actual result:
--------------
output:
a=b
c=d
a=c
a<>e
c<>e
