cfea172544 work around issue in MARC::Charset
Because of a bug in MARC::Charset 0.98, if a string to convert from
MARC-8 to UTF-8 has (a) one or more diacritics that (b) are only in character positions
128 to 255 inclusive, the resulting converted string is not in
UTF-8, but the legacy 8-bit encoding (e.g., ISO-8859-1).  As a result,
when such a record is converted to XML using ->as_xml_record(), the resulting
XML can be truncated at the offending character.  An example of such a record
is one that has a price in Briish pounds in the 260$c but no other diacritics.

b549d7e1f1 added StripNonXmlChars to C4::Charset
Added invocations of StripNonXmlChars to uses
of new_from_xml() that involve records
saved to Koha fields via MARC::Record->as_xml();
for batch jobs that work on MARC XML files
coming from external sources, StripNonXmlChars
should not necessarily be used, as it may
be better to reject a file or record if it
contains that kind of encoding error.

60a98d258a IMPORTANT - refactor MARC character set handling
* IsStringUTF8ish - determine if scalar contains a string in UTF8
* MarcToUTF8Record - convert MARC blob or MARC::Record to UTF8
* SetMarcUnicodeFlag - set appropriate MARC21 or UNIMARC field to
  indicate that record is in UTF-8.

Design points of this module include:

* No dependencies on other C4 modules, making it easier to add
  more test cases
* All character conversion code in one place
* Single entry point for doing a character conversion on a
  MARC record
* Capture of errors and warnings produced by Text::Iconv
  and MARC::Charset
* Start of support for guessing the source character set of
  a MARC record.

Several functions were moved from other scripts
or modules to C4::Charset:

* C4::Koha->FixEncoding (expanded and renamed
  MarcToUTF8Record)
* C4::Koha->char_decode5426
* fMARC8ToUTF8 from bulkmarcimport.pl (renamed
  _marc_marc8_to_utf8)

Several batch jobs were adjusted to use MarcToUTF8Record instead of
FixEncoding.

ea50c2acb6 Preliminary fix of the CGI.pm problem of always assuming that everything is
in ISO-8859-1.

A new C4::Charset module (tentative name) has been created to guess the
charset of a piece of HTML markup. The CGI programs will be modified to use
this module as they are encountered during translation.
