[TYPO3-english] Indexed search and UTF-8

[ktt]

Hello,

After conversion of a database to utf-8 collation utf8_general_ci, Indexed search behaviour become quite strange:
with
------------------------------
config.renderCharset = utf-8
config.metaCharset = utf-8
config.sys_language_uid = 0
config.language = dk
config.locale_all = dk_DK
------------------------------
it doesn't find a word which contains characters "æ,å.." etc.

With 
------------------------------
config.renderCharset = utf-8
config.metaCharset = iso-8859-1
config.sys_language_uid = 0
config.language = dk
config.locale_all = dk_DK
------------------------------
Indexed search splits/converts a search word "ansættelse" and writes:
'Search for "ansã" and "ttelse""'

And searches only for a "ttelse"..

Indexed search version - 2.12.0
TYPO3 - 4.5.2
MySQL client version: 5.0.51a

Localconf.php UTF-8 settings:
$TYPO3_CONF_VARS['SYS']['setDBinit'] = 'SET NAMES utf8;
$TYPO3_CONF_VARS['BE']['forceCharset'] = 'utf-8';

Could you advise what needs to be changed?
Since everywhere on the site encodings working correctly except
that strange word split in Indexed search.

Thank you in advance,
Kast A.
