Wrapper not supporting UTF-8

Questions Components & MVC

Hi everybody :slight_smile:
We installed new Apache2 server and PHP8.
When we try to access to our homepage, we have this fatal error :
**Fatal error**: Uncaught Laminas\Stdlib\Exception\RuntimeException: No wrapper found supporting "UTF-8" in [...]/vendor/laminas/laminas-stdlib/src/StringUtils.php:161

We tried to check if something is missing (for ex AddDefaultCharset UTF-8 in vhost files, …) but we don’t have any idea why this error occures…
Also tried to clean vendor and re-install libraries…
Maybe an extension is missing (or wrong one) ? I saw we should have iconv or mbstring, but we have them :
[PHP Modules] : bcmath, calendar, Core, ctype, curl, date, dom, exif, FFI, fileinfo, filter, ftp, gd, gettext, hash, iconv, intl, json, libxml, mbstring, mysqli, mysqlnd, openssl, pcntl, pcre, PDO, pdo_mysql, Phar, posix, readline, Reflection, session, shmop, SimpleXML, sockets, sodium, SPL, standard, sysvmsg, sysvsem, sysvshm, tokenizer, xml, xmlreader, xmlwriter, xsl, Zend OPcache, zlib

Any idea ? :slight_smile:

Hey @Issinia, welcome!

laminas-stdlib requires one of these extensions intl, iconv, or mbstring to properly work with multibyte strings.

You mentioned that these extensions are already installed, so my guess is they may not be enabled or configured correctly.

You can use this script to check.

<?php

$required_extensions = array_merge(...array_map(function(string $extension): array {
    return [$extension => extension_loaded($extension) ? 'true' : 'false'];
}, ['intl','iconv','mbstring']));

print_r([
    'required' => $required_extensions,
    'installed' => get_loaded_extensions()
]);

I recommend:

  1. Try to re-install the extensions using this command and then restart apache.

    sudo apt-get install php8.0-mbstring  php8.0-intl  php8.0-iconv

sudo service apache2 restart

  2. If the extension is already installed you should try to enable it. Either in the php.ini file or from command line.

    phpenmod -v 8.0 -s apache2 iconv

phpenmod -v 8.0 -s apache2 intl

phpenmod -v 8.0 -s apache2 mbstring

Hi !

First of all, thanks for your answer @ghostwriter :slight_smile:
I tried to run all your command without any new good new :frowning: I also tried to remove the 3 extensions and install them again.
So I removed them, installed them and also try to enable them.
With the php script, here what I get :
Array ( [required] => Array ( [intl] => false [iconv] => false [mbstring] => false ) [installed] => Array ( [0] => Core [1] => date [2] => libxml [3] => openssl [4] => pcre [5] => zlib [6] => filter [7] => hash [8] => json [9] => Reflection [10] => SPL [11] => session [12] => standard [13] => sodium [14] => apache2handler ) )
It looks they are installed, but why do they have a “false” status, is that correct ?

One additionnal question :
When I run the php -m command, I get approx 40 extensions, but with the php script, I found only 3 required and 15 installed. Is that correct ?
They are installed but not loaded ?

Thanks again for your support

Hey @Issinia :wave:t6:,

Hope you had a great weekend.

Looking at the result of the script, It looks like PHP did not load the extensions.

Let’s try adding Ondřej Surý’s PPA repositories and reinstalling PHP 8.0

sudo apt update
sudo apt install lsb-release ca-certificates apt-transport-https software-properties-common -y
sudo add-apt-repository ppa:ondrej/php
sudo add-apt-repository ppa:ondrej/apache2
sudo apt update
sudo apt install php8.0

Thanks !
It seems it was because the extension path in php.ini was wrong…
Now it seems this problem is solved…

I will probably open a new thread for the next error :sweat_smile:

Thanks for your support @ghostwriter
