iconv error when using "ß"

[skeutmeier]

Description

The following code:

<?php
$text = iconv('UTF-8', 'ASCII//TRANSLIT', 'ß');
var_dump($text);

Resulted in this output:

PHP Notice:  iconv(): Detected an illegal character in input string in /home/sebastian/inconv.php on line 2
bool(false)

But I expected this output instead:

string(2) "ss"

This is working correctly in PHP 8.1.12 but not in 8.1.13

PHP Version

PHP 8.1.13

Operating System

Ubuntu 20.04

https://3v4l.org/Ok0En shows that it also works in 8.1.13 as expected

So it looks like a glitch in one of the underlying libraries

Yeah, that's likely the issue. What are the values of ICONV_IMPL and ICONV_VERSION for your PHP 8.1.12 and 8.1.13 (you can also check phpinfo())?

IIRC iconv also relies on the locale-setting. See https://3v4l.org/eSWpk

Iconv implementation is glibc in both cases
with 8.1.12 I used version 2.17
with 8.1.13 it is version 2.31

Right.

with 8.1.12 I used version 2.17
with 8.1.13 it is version 2.31

So this is either a locale issue, or related to the glibc iconv update. I generally suggest to libiconv.
