TYPO3 Core

Hi,

you shouldn't use mb-functions direct., use t3lib_cs::conv_case() instead (you don't have to check for ($GLOBALS['TYPO3_CONF_VARS']['BE']['forceCharset'] for this conversion)

Hi Steffen
I got your point, t3lib_cs::conv_case() should be used and there we have conversion via mb_strtolower or via char_mapping.

However we have to explicitly set charset to use t3lib_cs::conv_case().
So we should use $GLOBALS['TYPO3_CONF_VARS']['BE']['forceCharset'] to determine the BE charset and if it is empty we use "iso-8859-1" encoding (actually we do here the same check as in t3lib_div::xml2array() so we match encoding with locallang labels).

I've uploaded new patch bug_0009501_1.diff

I've uploaded last correction - patch bug_0009501_2.diff - little correction of coding style for consistency with other code

Hi Vladimir,

you can get the actual charset very easy;
$GLOBALS['LANG']->charSet

with 4.2.2 this is always filled, so this should be enough ;-)

Hi, uploaded patch bug_0009501_3.diff includes last correction (with use of $GLOBALS['LANG']->charSet)

I've tested it with 4.1.7; 4.2.1; 4.2.2 it works well

there is a problem that the function can't be called static.
I changed it using $GLOBALS['LANG']->csConvObj->conv_case instead, new patch is attached

Fixed in 4.1, 4.2 and trunk (4.3),
