Version 1.3.6
Updated footer comment
Happy new year
Updated copyright headers. Omit CVS IDs.
Fixed bug #1989: For PQF SRU one char is stipped off query.
WRBUF updates
Update header. Copyright + yazproxy name
Expanded tabs in all source files. Added vim/emacs local variables trailer.
Added support for Z39.50 character set negotiation. This allows the proxy to act as a Z39.50 server supporting character set negotiation for backends not supporting it. New config element target-charset specifies encoding for target, and MUST be specified in order for any conversion to take place. Conversion also takes place for SRW/SRU clients that are negotiate implicitly to UTF-8.
If character set conversion fails - pass thru.. Unfortunately we don't know the encoding of SRU parameters.
New file needed for character set conversions
