[1] Added MARC-8 as an encoding choice on the target
administration page.
[2] Fixed TMPL coding errors.
[3] Set the correct encoding (as it happens, 'MARC-8')
for all of the English sample Z39.50 targets.
Documentation note: due to this patch and the ones from
Frederic, screenshots of the page for editing a Z39.50
target should be redone.
