What are the common mistakes to avoid when creating custom PHP functions for language-specific tasks?

One common mistake to avoid when creating custom PHP functions for language-specific tasks is not properly handling character encoding. It's important to ensure that the function is able to handle different character sets, especially when dealing with multilingual content. To solve this issue, use functions like mb_convert_encoding() or utf8_encode() to properly handle encoding within your custom function. 

// Example of handling character encoding within a custom PHP function
function customLanguageFunction($input) {
    // Convert input to UTF-8 encoding
    $input = mb_convert_encoding($input, 'UTF-8');
    
    // Your custom function logic here
    
    return $output;
}
