Add a line break in Woocommerce Product Titles

Let's say my product title is:

Brown Colored Leather Shoes

But based on my column width the title looks like this:

Brown Colored Leather
Shoes

I know it's possible to do a character replacement so that a "|" in the backend becomes a line break <br/>. But I don't know how.

I want it to look like this

Brown Colored
Leather Shoes

I found these references:

• Adding a break to product title on shop pages for a certain length

Is it possible to add a line break to WC products long titles?

2020 revision - Still works on Wordpress 5.5.1 with WooCommerce 4.4.1

Using this custom function hooked in the_title filter hook will do the job (replacing a pipe character | by a <br> in product titles):

add_filter( 'the_title', 'custom_product_title', 10, 2 );
function custom_product_title( $title, $post_id ){
    $post_type = get_post_field( 'post_type', $post_id, true ); 

    if( in_array( $post_type, array( 'product', 'product_variation') ) ) {
        $title = str_replace( '|', '<br/>', $title ); // we replace "|" by "<br>"
    }
    return $title;
}

Code goes in function.php file of your active child theme (or theme) or also in any plugin file.

Code is tested on Woocommerce 3+ and works.

Now you can target different product pages with the WC conditionals tags as is_product(), is_shop(), is_product_category() or is_product_tag() (and many others)…

The full answer working as Nov 2019 with Wordpress 5.2.4:

//ADD LINE BREAK 
add_filter( 'the_title', 'custom_the_title', 10, 2 );
function custom_the_title( $title, $post_id ) {
    $post_type = get_post_field( 'post_type', $post_id, true );
    if( $post_type == 'product' || $post_type == 'product_variation' )
        $title = str_replace( '|', '<br/>', $title ); // we replace '|' by '<br>'
    return $title;
}
