# Feature: #72337 - Charset Conversion Autodetection {#feature-72337-charset-conversion-autodetection}

See [forge#72337](https://forge.typo3.org/issues/72337)

## Description {#description}

The Charset Converter which is used to handle multi-byte charset conversions now
always uses `mbstring`. In case `mbstring` is not present a polyfill will kick in.

## Impact {#impact}

The options `$TYPO3_CONF_VARS['SYS'][t3lib_cs_utils]` and
`$TYPO3_CONF_VARS[SYS][t3lib_cs_convMethod]` have no effect anymore and can be
removed.
