Non latin characters in name

Question

My name contains an ö character: Lövgren

This is printed in my name in the normal name entry in my passport like this: LÖVGREN

In the Visa application form on visa.kdmid.ru however I am asked to enter a version of my name without the Ö, which is printed on the bottom of the page in my passport, like this: LOEVGREN

Which version of the name should go in the invitation letter, LÖVGREN or LOEVGREN?

Answer 1

The customer service for Read Russia tells me that the form LOEVGREN is the international accepted form and that this should work on the Visa support document.
