Henri-Damien LAURENT b5a1060788 Improving encoding Support for z3950 clients. 
Adding encoding for z3950 server information.
Uses Text::Iconv for conversion (ISO6937 and ISO_5428 and ISO5427)
For ISO 5426 (ANSEL or MARC-8) new char_decode5426 based on marc4j tool.

Not Tested on LOC or any USMARC z3950 source. But tested OK on BNF and SUDOC.

that feature currently does not deal with items and biblioitems changes
correctly, those tags are specifically excluded from the list prepared
