[turba] turba does not show correct charset

[Frank Purmann]

I have upgraded horde (turba, imp, etc) to

# Horde: 3.1.2
# Imp: H3 (4.1.1)
# Kronolith: H3 (2.1)
# Mnemo: H3 (2.1)
# Nag: H3 (2.1)
# Turba: H3 (2.1) 

The problem is that addresses in turba do not display correctly in Korean (they
have done it with the old version horde 2.1). The same happens when adding a
address with the new version in Korean.
Menus and reading emails in Korean does work properly.
Our default charset in MySql is iso-8859-1 (version 3.23 I know its old but it
worked with the previous version of horde).

It seems to me that when reading the data from MySql the conversion back to the
Korean charset does not work.
