Iconv problem

[prolic]

Test-Case: php -d error_reporting=22527 -d display_errors=1 -r 'var_dump(iconv("UTF-8", "UTF-8//IGNORE", "This is the Euro symbol '\''€'\''."));'

output: Notice: iconv(): Wrong charset, conversion fromUTF-8' to UTF-8//IGNORE' is not allowed in Command line code on line 1

So I customized the dockerfile to:

FROM prooph/php:7.1-fpm-opcache
RUN apk add gnu-libiconv --update-cache --repository http://dl-cdn.alpinelinux.org/alpine/edge/testing/ --allow-untrusted
ENV LD_PRELOAD /usr/lib/preloadable_libiconv.so php

Let's test this:

output: string(30) "This is the Euro symbol '€'."

I think the LD_PRELOAD fix is not a good solution for our prooph Docker images. Maybe mb_convert_encoding($text, 'UTF-8', 'UTF-8'); does the same if you want to remove invalid UTF-8 characters?

I ran into this issue due to work, not sure if this happened in their code or in third party library. Would need to double check.

I checked again, the iconv stuff is used by wordpress.

Ok but I don't know how to solve this and I think it's not related for our Docker images, because they are only intended for development and may be only a blueprint for production.

I never said the word production. Iconv is used by wordpress. This is also true for development mode. So I can't use these docker images for a local wp installation. With the fix i provided it works.

Maybe this is solved in the new Docker images >= PHP 7.4 with Alpine 3.15.
