Edit report at https://bugs.php.net/bug.php?id=80671&edit=1 ID: 80671 User updated by: alec at alec dot pl Reported by: alec at alec dot pl Summary: mb_convert_encoding() throws ValueError unexpectedly Status: Open Type: Bug Package: mbstring related PHP Version: 8.0.1 Block user comment: N Private report: N New Comment: BTW, regarding the error message, the encoding is not invalid, it is unsupported. Previous Comments: ------------------------------------------------------------------------ [2021-01-26 07:37:41] alec at alec dot pl Description: ------------ PHP Fatal error: Uncaught ValueError: mb_convert_encoding(): Argument #3 ($from_encoding) contains invalid encoding "WINDOWS-1253". Before PHP8 it never threw even a warning, so to me it looks like a BC break which: 1. should throw a warning in PHP 8.0, before it could switch to a fatal error in 8.1. 2. should be mentioned in the migration guide and the documentation.
