Bug 12438 - Bad encoding in acquisition basket

We noticed a bad encoding (diacritics replaced by <?>) in acquisition basket when updating a server to Debian Wheezy.
We found it comes from a query containing biblio.title twice.
Maybe the mysql newer version creates this side-effect.

Test plan :
- Create an order on a record containing a diacritic in title
- Look at the basket : cgi-bin/koha/acqui/basket.pl?basketno=x
=> Without the patch the record title is bad encoded (with <?>)
=> With this patch the record title is well encoded
- Check also basket CSV export

Good catch!
Works as expected, passes tests and QA script.

Duplicated biblio.title is a (minor) bug, and should be removed.

The side-effect of it solving an encoding problem might be seen
as problematic: it hides a real problem.
The efforts on 11944 actually solve this encoding problem (11944
merged into master actually fixes this), so I'm pushing it, for
a short term solution for stable, with the hope that we will soon
have 11944 pushed.
BTW, non-diacritic but non-ASCII characters are not broken either.
