As a native German speaker, I’d like to start with a little history. The two dots above the umlauts originate from a small e. In the Middle Ages, umlauts were still represented by ae, oe and ue. After some time, the e was written directly above the vowel. To save time, one wrote two dashes instead of the e at first and finally two dots. Over time, this became the official version. Texts are not only easier to read this way because we are used to this typeface, but also dictionaries only display words using ä/ö/ü/ß.
In recent times, when international communication became more and more important, with typewriters and computer keyboards, where space is limited and because of the history of these letters, it became accepted to use the spelling vowel+e in international documents.
However, in German-speaking countries, the letters “ä/ö/ü/ß” exist and for formal texts and communication, there is no alternative. For example, students in school or university can’t just hand in a paper using ue instead of ü.
To give another example, in German exist two different last names: Goethe & Göthe. They are not the same. Therefore I wouldn’t go as far and say it’s always correct to use ue instead of ü, but that it can be accepted if you don’t have any other way, @ejferguson.
Since the journals focus specifically on writing, our tutors do correct these things, even if to you it seems like something minor or annoying. Behind every journal correction, there is a human and I like Amandine’s suggestion to just add a sentence at the top or bottom of your text, letting the tutor know that they don’t need to correct the umlaut.
