My website sells a lot of products to people in Europe, and as is to be expected, some of the customer names feature diacritical marks. Unfortunately, the names with diacritical marks don't show on the delivery and invoice. It just removes the whole name, even the parts that don't feature diacritical marks.
Here's some example of names with diacritical marks: Artūras Nalivaika, Jurgita Dapkevičiūtė
What can I do?
