It seems that although your iconv library path is in your LIB path, the library was not in the list of libraries being linked against: "iconv.lib" isn't in this list: link -out:blib\arch\auto\Text\Iconv\Iconv.dll -dll -nologo -nodefaultlib -release -libpath:"C:\Perl\lib\CORE" -machine:x86 Iconv.obj C:\SiteMinderPerl\lib\CORE\perl56.lib oldnames.lib kernel32.lib user32.lib gdi32.libw inspool.lib comdlg32.lib advapi32.lib shell32.lib ole32.lib oleaut32.lib netapi32.lib uuid.lib wsock32.lib mpr.lib winmm.lib version.lib odbc32.lib odbccp32.lib msvcrt.lib -def:Iconv.def So the build process would have found it if it had looked for it, but it wasn't actually looking. To tell the build process to look for the library, start again with something like: perl Makefile.PL LIBS=iconv.lib (or use something like "perl Makefile.PL LIBS=C:\libiconv\lib\iconv.lib" if your libiconv library path isn't in %LIB%.) - Steve This email has been scanned for viruses and content by the Radan Computational Webshield Appliances.

I also found that Text-Iconv-1.4 had build problems, even with the
LIBS=... bit. It obviously needs a little work to make it more
Win32-friendly.
You were previously using Text-Iconv-1.2. That builds fine for me, so
give that a go.

clearing the utf8 flag
I have a program that reads and writes (among others) strings that
should be utf8 encoded. I say "should", because somewhere deep
inside the dark corners of that program, sometimes, the utf8 flag on
a string is lost. (I'm still investigating where, tips to attack
such a problem are welcome.)
When writing the string, the program clears the utf8 flag
and writes a simple string of octets using:
$s = encode("utf8", $s) if $s =~ /[^\x00-\x7f]/;
$n = length($s); # yes, we need length in bytes
...
print $s;
Why would someone test for pure 7-bit strings instead of:
$s = encode("utf8", $s) if Encode::is_utf8($s);
which seems superior to avoid double utf8 encodings,
should the utf8-flag be lost. And it's faster.
Or even simply: Encode::_utf8_off($s)
The problem is that I'm usually wrong. Am I this time?
Am I missing something? Or do I need more coffee?

Even when you try to set UTF-8 flag on strings which consists entirely
of ASCII ( /^[\x00-\x7f]$/ ) the UTF-8 will not be on. See "The UTF-8
flag" section of 'perldoc Encode'. Here is the short summary.
perldoc Encode
o When you decode, the resulting utf8 flag is on unless you can
unam-
biguously represent data. Here is the definition of
dis-ambiguity.
After "$utf8 = decode('foo', $octet);",
When $octet is... The utf8 flag in $utf8 is
-
In ASCII only (or EBCDIC only)OFF
In ISO-8859-1 ON
In any other Encoding ON
-
As you see, there is one exception, In ASCII. That way you
can assue
Goal #1. And with Encode Goal #2 is assumed but you still
have to be
careful in such cases mentioned in CAVEAT paragraphs.
When writing the string, the program clears the utf8 flag
and writes a simple string of octets using:
$s = encode("utf8", $s) if $s =~ /[^\x00-\x7f]/;
$n = length($s); # yes, we need length in bytes
...
print $s;
If what you need is byte length, you can simply "use bytes" as follows.
binmode is for print().
use bytes (); # avoid imports
binmode STDOUT => ":utf8";
my $s = "\x{5c0f}\x{98fc} \x{5f3e}";
# ...
my $n = length($s);ch
my $l = bytes::length($s);
# ...
print $s;
Why would someone test for pure 7-bit strings instead of:
$s = encode("utf8", $s) if Encode::is_utf8($s);
For most cases you don't have to and you should not have to (unless you
maintain Encode and/or perl :). Complex it may be, the internal UTF-8
flag was the best way to harness UTF-8 while keeping legacy,
byte-oriented scripts compatible.
which seems superior to avoid double utf8 encodings,
shoue ld the utf8-flag be lost. And it's faster.
Or even simply: Encode::_utf8_off($s)
The problem is that I'm usually wrong. Am I this time?
Am I missing something? Or do I need more coffee?
I have to admit Encode and Perl 5.8-way of handling Unicode needs more
recipes (Perl Cookbook 2nd Ed. does cover that issue on Ch. 8 but it
was hardly enough).
