Symbols

Hi @tjos123,

Maybe you were using a different PDF Invoices plugin before? I ask this because the default PDF engine we use (dompdf) is not compatible with emojis yet. See: Add Emoji support (Issue #1698)

The best thing we can do is offering a code snippet to remove the emojis from the PDF documents. Let me know if this is enough for you.

Hi @yordansoares. I certainly only used this plugin. It’s good enough for my usage, so I have never tried others. But yeah, it’s rather strange too as I would have thought that the emojis aren’t supported.

Yes if you could share the code snippet for me to test out. Thank you.

Hi @tjos123,

Please add this code snippet to your site, in order to remove the emojis from the product names on the PDF documents:

/**
 * PDF Invoices & Packing Slips for WooCommerce:
 * Remove emojis, emoticons and other non-printable characters from the product names on the PDF documents
 */
add_filter( 'wpo_wcpdf_html_filters', function( $filters ) {
	$filters[] = array( 'woocommerce_order_item_name', 'wpo_wcpdf_remove_emojis_from_item_name', 999, 3 );
	return $filters;
} );
function wpo_wcpdf_remove_emojis_from_item_name ( $item_name, $item, $is_visible ) {
	
	// Emojis
	$regex_emojis = '/[[:^print:]]/';
	$item_name = preg_replace( $regex_emojis, '', $item_name );
	
	// Emoticons
	$regex_emoticons = '/[\x{1F600}-\x{1F64F}]/u';
	$item_name = preg_replace( $regex_emoticons, '', $item_name );
	
	// Miscellaneous Symbols and Pictographs
	$regex_symbols = '/[\x{1F300}-\x{1F5FF}]/u';
	$item_name = preg_replace( $regex_symbols, '', $item_name );

	return $item_name;
}

Let me know if it worked! ??

Hi @yordansoares! Sorry I wasn’t clear at first. I was referring to the emojis on the meta of the product.

Hi @tjos123,

Oh, I thought it was happening only in the item name. Please replace my previous code snippet to remove the emojis and other non-printable characters from the formatted meta on the PDF documents:

/**
 * PDF Invoices & Packing Slips for WooCommerce:
 * Remove emojis, emoticons and other non-printable characters from the formatted meta on the PDF documents
 */
add_filter( 'wpo_wcpdf_html_filters', function( $filters ) {
	$filters[] = array( 'woocommerce_order_item_get_formatted_meta_data', 'wpo_wcpdf_remove_emojis_from_item_meta', 999, 2 );
	return $filters;
} );
function wpo_wcpdf_remove_emojis_from_item_meta( $formatted_meta, $item ) {
	foreach( $formatted_meta as $key => $meta ){
		// Emojis
		$regex_emojis = '/[[:^print:]]/';
		$value = preg_replace( $regex_emojis, '', $meta->value );

		// Emoticons
		$regex_emoticons = '/[\x{1F600}-\x{1F64F}]/u';
		$value = preg_replace( $regex_emoticons, '', $value );

		// Miscellaneous Symbols and Pictographs
		$regex_symbols = '/[\x{1F300}-\x{1F5FF}]/u';
		$meta->value = preg_replace( $regex_symbols, '', $value );
		
		$meta->display_value = $meta->value;
		$formatted_meta[$key] = $meta;
	}

	return $formatted_meta;
}
