Hi, I guess the following question has already been answerd somewher but I
couldn't find it on the archive. A search feature for the archive would be
great. After reading 20-30 mails I started to get tired of it. Has anyone
seen a a mail-archive crawler which can do a search. (That sound almost
like a fun script to write)
More seriously. I am using 5.6.3 on windows from activestate. I do the
following.
I don't think you are. As far as I am aware there is only perl5.6.1
there isn't a .3 subversion yet.
my $ole_object = ..... ;
my $unicode_string = $ole_object->GetUnicodeString() ;
OLE objects are a Win32 thing. You would be better off asking on
one of the Win32 aware ActiveState lists. We would at least need
to know how you created $ole_object so we can lookup the code
that gets the string.
print length($unicode_string), "\n" ;
# prints 17, which is the length of the unicode string
Cool - but are you sure you got the real string?
use byte () ;
print byte::length($unicode_string), "\n" ;
# prints 17, wow, the string is japanese I expect 34
The byte:: hackery is _very_ confusing to all concerned.
It returns the length the string happens to be in perl's internal
encoding. That may be either iso-8859-1 or UTF-8. If the original
"japanese" happened to be all iso-8859-1 even though it used to be
2-bytes/char it will be held (normally) by perl as 1-byte per-char.
You will also get 1-byte/char if (as I suspect is happening here)
->GetUnicodeString has converted things it does not understand to '?'.
print $unicode_string ;
# prints ??????????????? on the console
Hmm - as perl5.6 does not have "smart" Unicode IO (perl5.8 does),
this suggests that string is actually '?' x 17 - i.e. you got "junk"
back from the OLE call.
print FILE $unicode_string ;
# prints ??????????????? in the file
<<<<<<
Likewise.
What the script is to do is:
1/ get a unicode string from an Ole object
Contact OLE expert and find out if that works.
2/ read a unicode string from a file
For perl5.6 file has to be in UTF-8 and you need to do some hackery
(which was so horrible I can't recall it).
For perl5.8 this is easy - it was a major goal of perl5.8.
3/ compare both strings and act upon the comparison
Once you have two Unicode strings this is easy.
if the string I get from ole _is_ unicode (and it seems so)
What leads you to that conclusion?
how can I
flatten it to binary? I tried with unpack without success.
Nadim.
