Are there any common pitfalls to be aware of when setting up a PHP forum in a non-English language?

One common pitfall when setting up a PHP forum in a non-English language is forgetting to properly set the character encoding to support special characters. To solve this, you can add the following line of code to your PHP script to set the character encoding to UTF-8:

```php
header('Content-Type: text/html; charset=utf-8');
```

Another common issue is not translating all the text strings used in the forum interface. Make sure to use a language file or translation tool to properly localize all the text displayed on the forum.
