There is a bug in displaying citations containing German Umlaut characters in the two "Pontifical" styles in Logos.
I stumbled over this when looking up the so-called "Einheitsübersetzung", a German language Bible LLS:EINHEIT2 : The citation styles Pontifical Bible Institute and Pontifical Athenaeum Regina Apostolorum put part of the citation text into a small superscript font like a footnote marker (which is different to other citation styles, and may or may not be correct) but this breaks for German Umlaut characters äöü / ÄÖÜ in Logos 7.5 Beta 3 (possibly earlier and/or live versions as well, but I don't use those citation styles normally)
This formatting is not carried over to the forum editor, which has normal font:
Die Bibel. Einheitsübersetzung der Heiligen Schrift. (Stuttgart Herausgegeben im Auftrag der Bischöfe Deutschlands, Österreichs, der Schweiz, des Bischofs von Lüttich, des Bischofs von Bozen-Brixen, des Rates der Evangelischen Kirche in Deutschland und der Deutschen Bibelgesellschaft. Ausgabe in neuer Rechtschreibung.1999–).
(for those wondering: the superscript text says this bible was published according to the order of Roman-Catholic bishops of Germany, Austria, Switzerland, Luttich in Belgium and Bozen in Italy, i.e. all German-speaking territories in Europe, the Protestant Church in Germany and the German Bible Society - which explains its name "Unity-Translation" - and that it was published in New German Spelling)
Pasting it into Word 2016 on Windows 10 retains the superscript formatting, but it uses Word's default font Calibri which is capable of displaying Umlauts in superscript (Logos left, Word right)
