Bug description: PB serialization ascii code greater than 127
Description:
------------
Hi,
There's a little bug with strings serialization, for strings containing
characters with ascii code greater than 127 (with HP-UX v11).
We found that the problem is located in function :
php_wddx_serialize_string.
There is a line of code like :
if (iscntrl((int)*p) {
When casting character (*p) to int for values greater than 127 (witch are
considered negative) there is a sign extension so character 'ρ'(ascii code
0xf0) become integer 0xfffffff0.
But the function iscntrl expects an integrer between 0 and 255, or the
result is unpredictable.
The problem can be fixed by modifying the line above like :
if(iscntrl((int)(unsigned char)*p) {
Best Regards

Reproduce code:
---------------
<?php
print "<u>Without locale :</u><br><br>";
print "ΰβδηιθκλξοτω ΐΒΔΙΘΚΛΞΟΤΩ ρ Ρ" . "<br>\n";
print wddx_deserialize(wddx_serialize_value("ΰβδηιθκλξοτω ΐΒΔΙΘΚΛΞΟΤΩ ρ
Ρ"));
print "<br><hr><br>";
print "<u>With locale (fr_FR.iso88591) :</u><br><br>";
setlocale(LC_CTYPE, "fr_FR.iso88591");
print "ΰβδηιθκλξοτω ΐΒΔΙΘΚΛΞΟΤΩ ρ Ρ" . "<br>\n";
print wddx_deserialize(wddx_serialize_value("ΰβδηιθκλξοτω ΐΒΔΙΘΚΛΞΟΤΩ ρ
Ρ"));
?>
Expected result:
----------------
Result :
Without locale :
ΰβδηιθκλξοτω ΐΒΔΙΘΚΛΞΟΤΩ ρ Ρ
ΰβδηιθκλξοτω ΐΒΔΙΘΚΛΞΟΤΩ ρ Ρ
-----------------------------------------------------------
With locale (fr_FR.iso88591) :
ΰβδηιθκλξοτω ΐΒΔΙΘΚΛΞΟΤΩ ρ Ρ
ΰβδηιθκλξοτω ΐΒΔΙΘΚΛΞΟΤΩ ρ Ρ
Actual result:
--------------
Result :
Without locale :
ΰβδηιθκλξοτω ΐΒΔΙΘΚΛΞΟΤΩ ρ Ρ
ΰβδηιθκλξοτω ΐΒΔΙΘΚΛΞΟΤΩ ? Ρ
-----------------------------------------------------------
With locale (fr_FR.iso88591) :
ΰβδηιθκλξοτω ΐΒΔΙΘΚΛΞΟΤΩ ρ Ρ
ΰβδηιθκλξοτω ΐΒΔ?ΘΚΛΞΟΤΩ ρ Ρ
