Answer 1

To answer my own question - i found the following solution:

setting the locale environment variable with PHP

$locale='de_DE.UTF-8';
setlocale(LC_ALL,$locale);
putenv('LC_ALL='.$locale);
echo exec('locale charmap');

This sets to / returns UTF-8. So i'm able to pass special characters and umlauts to linux shell commands.

Answer 2

I had the similar problem. My program was returning me some German letters like: üäöß. Here is my code:

$programResult = shell_exec('my script');

Variable $programResult is containing German umlauts, but they were badly encoded. In order to encode it properly you can call utf8_encode() function.

$programResult = shell_exec('my script');
$programResult = utf8_encode($programResult);

Answer 3

This solves it for me (source: this comment here):

<?php
putenv('LANG=en_US.UTF-8'); 
$command = escapeshellcmd('python3 myscript.py');
$output = shell_exec($command);
echo $output;
?>
