[TYPO3-english] utf-8 data is showing wrong charachters

[TSniper]

i developed an php code to list data from an table 'title_company'
this table use encoding = utf8_unicode_ci
in this table i have listed the names of items and companies, only the problems that thos names are in polska language.

the word like this
sprężarki 
is transformed to :
spr??arki.

When i open the database, the right charachters are there.
I tried to add this in localconfiguration.php
		't3lib_cs_convMethod' => 'mbstring',
		't3lib_cs_utils' => 'mbstring',
but didn'ts wrok

i tried also :
In the Install-Tool, BE[forceCharset] is set to utf-8.
In Typoscript, i have set config.renderCharset = utf-8

don't work neither.


Any ideas how to get the right content from this table.
