Dear Doran, Ed, Bill and others:
thank you for your replies. I installed MARC::Charset using the CPAN
module to ensure dependencies. I don't know why it is not working well.
If you have some tricks, please let me know.
Although I'm interested in MARC-8 -> UTF-8 conversion in memory, a good
way to do the conversion seems to be yaz-marcdump. Unfortunately it
seems unable to work with stdin as input, so I need to use a temp file
for each record: a heavy conversion process.
BTW, I'm going to manage latin-1, latin-2 and arabic MARC records.
Bye. Stefano

Hi Stefano,
Installing the MARC::Charset module can be a bit problematic for the
casual Perl user, due to the prerequisites. However if you need to do
a
MARC-8 to UTF-8 conversion, that's probably the best tool available.
The issue with MARC-8 conversions is that MARC-8 is only really used
for
encoding bibliographic records and with its use of combining diacritics
and escape sequences, it is more complex than the typical 8-bit
character set [1]. Most of the software development in the area of
library-centric character sets is done by ILS vendors, who typically
don't make their efforts available in the form of freely available Perl
modules.
You didn't say mention why you were wanting to do a character set
conversion. If you just need a "quick and dirty" conversion for
ephemeral display of bibliographic information on a web page, you might
look at alternatives such as converting from MARC-8 to Latin-1 (ISO
8859-1). That's a potentially lossy conversion, however if most of
your
records are Italian, the Latin-1 repertoire should suffice. There are
some available Perl routines that should handle that conversion [2].

Subject: MARC-8 to UTF-8 conversion
Hi, I'm trying to convert MARC-8 records to UTF-8 on the fly.
March::Charset doesn't work for me.
Any suggestion? Also a command line way can be good for my purposes.
TIA. Stefano
