Description

Spammers often enter invalid utf-8 characters in forms and submit them. This leads to problems when sending the data to an API by json-encoding them:

json_encode error: Malformed UTF-8 characters, possibly incorrectly encoded

TYPO3 should provide a way to validate if form field values contain valid utf-8 characters only.

Either the Text validator could be extended, or a new UTF-8 validator could be introduced.

No data to display
