Deprecation: #75327 - $TSFE->csConvObj and $TSFE->csConv()

See Issue #75327

Description

The public property csConvObj and the public method csConv() inside the TypoScriptFrontendController PHP class have been marked as deprecated.

Impact

Calling $TSFE->csConv() will trigger a deprecation log entry.

Affected Installations

Any TYPO3 installation which uses the property or the method directly.

Migration

If a charset conversion is necessary, the conversion can be done directly by instantiating the charset converter class.

$from = 'iso-8859-15';
/** @var \TYPO3\CMS\Core\Charset\CharsetConverter $charsetConverter */
$charsetConverter = GeneralUtility::makeInstance(\TYPO3\CMS\Core\Charset\CharsetConverter::class);
$output = $charsetConverter->conv($str, $charsetConverter->parse_charset($from), 'utf-8');
