Iconv fails to transform UTF-8 to ASCII/TRANSLIT

[amari-at4]

API Platform version(s) affected: 2.5.5

Description
When try to use the transliteration with iconv throw this notice "php Notice: iconv(): Wrong charset, conversion from UTF-8' to ASCII//TRANSLIT' is not allowed" and Api Platform throws an Exception

How to reproduce

$text="Texto en español"
$new_text = iconv('UTF-8', 'ASCII//TRANSLIT', $text);

Possible Solution
As commented here it's an Alpine bug. to fix this it's necessary to add to the Dokerfile this lines:

RUN apk add --no-cache --repository http:https://dl-cdn.alpinelinux.org/alpine/edge/community/ --allow-untrusted gnu-libiconv
ENV LD_PRELOAD /usr/lib/preloadable_libiconv.so

Thanks for the report and the workaround! I suggest to wait for this package to be marked as stable by Alpine before we change this.
